16 innoextract is a tool that can extract installer executables created by
17 Inno Setup.
18 innoextract will extract files from installers specified on the command
20 line.
21 To extract a multi-part installer with external data files, only the
23 executable (.exe) file needs to be given as an argument to innoextract.
24

75 -- Treat all arguments after this one as files, even if they begin
76 with a dash.
77 --check-password
79 Abort processing if the password provided using the --password
80 or --password-file option does not match the checksum stored in
81 the installer.
82 The password checksum used for this check can be retrieved using
84 the --show-password option.
85 --codepage CODEPAGE
87 Non-Unicode versions of Inno Setup store strings in an unspeci‐
88 fied encoding. By default, innoextract will guess the encoding
89 from the installer's language list, falling back to Win‐
90 dows-1252. This option can be used to override that guess by
91 specifying a non-zero Windows codepage number to use.
92 On non-Windows platforms, innoextract will ignore the system
94 locale and always use UTF-8 as the filesystem and standard out‐
95 put encoding - the --codepage option only changes the input
96 encoding. However, using codepage number "65001" instructs
97 innoextract to assume all strings are already encoded as UTF-8
98 and to output them without conversion.
99 This option has no effect with Unicode-enabled installers, which
101 always use UTF-16LE. Invalid UTF-16 data is represented using
102 the WTF-8 encoding which is a straightforward extension of UTF-8
103 to represent unpaired UTF-16 surrogate code units.
104 --collisions ACTION
106 Inno Setup installers can contain duplicate files with the same
107 name. This option tells innoextract what to do when such a col‐
108 lisions is encountered. Valid actions are:
109 "overwrite"
112 Extract only one of the colliding files. The choice is
113 done similar to how Inno Setup overwrites files during
114 installation. This is the default.
115 "rename"
117 Rename files that would be overwritten using the "over‐
118 write" action by appending a suffix comprised of the
119 file's language, its architecture, the component it
120 belongs to and/or a number to make the filename unique.
121 The language suffix (if applicable) is also appended to
122 the default file that would have been extracted with the
123 "overwrite" action.
124 "rename-all"
126 Rename all colliding files by appending a suffix com‐
127 prised of the file's language, its architecture, the com‐
128 ponent it belongs to and/or a number to make the filename
129 unique. The complete suffix is appended to both files
130 that would have been overwritten using the "overwrite"
131 action and to those that would have overwritten other
132 files.
133 "error"
135 Exit when a collision is detected.
136 Rename rules:
138 1. If the component is not the same for all files in the colli‐
140 sion set (all files with the same filename), "#" (without
141 quotes) followed by the component id is appended to all files
142 that are specific to a single component.
143 2. If the language is not the same for all files in the colli‐
145 sion set, "@" (without quotes) followed by the language id is
146 appended to all files that are specific to a single language
147 unless that language matches the default language specified by
148 the --default-language. While the suffix is omitted for the
149 default language, no numbered suffix is added in it's place
150 unless needed to make the filename unique.
151 3. If the architecture is not the same for all files in the col‐
153 lision set, "@32bit" or "@64bit" (without quotes) is appended to
154 all files that are specific to a single architecture.
155 4. If no suffix was added by the previous steps, or if the file‐
157 name is not yet unique, "$" (without quotes) followed by the
158 lowest integer (starting at 0) to make the filename unique is
159 appended.
160 With the "rename" action, steps 1 and 3 are only applied to
162 files that would have been overwritten by the "overwrite" action
163 while "rename-all" applies them to all files in the collision
164 set.
165 -c, --color[=ENABLE]
167 By default innoextract will try to detect if the terminal sup‐
168 ports shell escape codes and enable or disable color output
169 accordingly. Specifically, colors will be enabled if both stdout
170 and stderr point to a TTY, the TERM environment variable is not
171 set to "dumb" and the NO_COLOR environment variable is unset.
172 Pass 1 or true to --color to force color output. Pass 0 or false
173 to never output color codes.
174 -V, --data-version
176 Print the Inno Setup data version of the installer and exit
177 immediately.
178 The version printed using this option is the one stored in the
180 setup file and can differ from the version printed with other
181 actions as the stored data version is not always correct.
182 This option can be used to determine if a file is an Inno Setup
184 installer without loading any compressed headers.
185 This option cannot be combined with any other action.
187 --default-language LANG
189 Set a language as the default.
190 With --collisions=overwrite (the default) this will change the
192 choice of which file to keep to always prefer the given lan‐
193 guage. In effect, --default-language behaves almost like --lan‐
194 guage, except that files are extracted for all languages if they
195 have different names.
196 When using the --collisions=rename option, --default-language
198 chooses a language for which the files should keep the original
199 name if possible.
200 --dump Don't convert Windows paths to UNIX paths and don't substitute
202 constants in paths.
203 When combining --dump with --extract innoextract will not ensure
205 that the paths don't point outside the destination directory.
206 Use this option with caution when handling untrusted files.
207 -m, --exclude-temp
209 Don't extract files that would have been deleted at the end of
210 the install process. Such files are marked with [temp] in the
211 file listing.
212 This option takes precedence over --include and --language: tem‐
214 porary files are never extracted when using the --exclude-temp,
215 even if they match the selected language or include expressions.
216 -e, --extract
218 Extract all files to the current directory. This action is
219 enabled by default, unless one or more of the --list,
220 --list-sizes, --list-checksums, --test, --list-languages,
221 --gog-game-id, --show-password or --check-password actions are
222 specified.
223 By default innoextract will continue after encountering file
225 checksum errors. The --extract option can be combined with
226 --test to abort on checksum errors.
227 -n, --no-extract-unknown
229 By default innoextract will try to extract installers with an
230 unknown Inno Setup data version by treating it as the closest
231 known version. This option tells innoextract to abort instead.
232 -g, --gog
234 Try to process additional .bin files that have the same basename
235 as the setup but are not actually part of the Inno Setup in‐
236 staller. This is the case for newer multi-part GOG.com install‐
237 ers where these .bin files are RAR archives, potential encrypted
238 with the MD5 checksum of the game ID (see the --gog-game-id
239 option).
240 Extracting these RAR archives requires rar, unrar or lsar/unar
242 command-line utilities to be in the PATH.
243 The --list, --test, --extract and --output-dir options are
245 passed along to unrar/unar, but other options may be ignored for
246 the RAR files. For multi-part RAR archives, the --test requires
247 a writable output directory for temporary files.
248 Note that is option is geared towards GOG.com installers. Other
250 installers may come be bundled with different extraneous .bin
251 which this option might not be able to handle.
252 This option also forces re-assembly of GOG Galaxy file parts.
254 See the --no-gog-galaxy option for details.
255 --no-gog-galaxy
257 Some GOG.com installers contain files in GOG Galaxy format
258 (split into multiple parts that are individually compressed)
259 which are re-assembled using post-install scripts. By default
260 innoextract will try to re-assemble such files if it detects a
261 GOG.com installer. This option disables that.
262 GOG.com installers are detected using the publisher and URL
264 fields in the setup headers. Use the --gog option to force
265 reassembly for all installers.
266 --gog-game-id
268 Determine the ID used by GOG.com for the game contained in this
269 installer. This will only work with Galaxy-ready GOG.com in‐
270 stallers.
271 This option can be combined with --silent to print only the game
273 ID without additional syntax that would make consumption by
274 other scripts harder.
275 The --gog-game-id action can be combined with --list, --test,
277 --extract and/or --list-languages. If --silent and --gog-game-id
278 are combined with --list and/or --list-languages, the game ID
279 (or an empty line) will be printed on it's own line before the
280 file list but after the language list.
281 For newer multi-part GOG.com installers the .bin files are not
283 part of the Inno Setup installer but instead are RAR archives.
284 Some of these RAR files are encrypted, with the password being
285 the MD5 checksum of the game ID:
286 innoextract --gog-game-id --silent setup_....exe | md5sum |
288 cut -d ' ' -f 1
289 -h, --help
291 Show a list of the supported options.
292 -I, --include EXPR
294 If this option is specified, innoextract will only process files
295 whose path matches EXPR. The expression can be either a single
296 path component (a file or directory name) or a series of succes‐
297 sive path components joined by the OS path separator (\ on Win‐
298 dows, / elsewhere).
299 The expression is always matched against one or more full path
301 components. Filtering by parts of filenames is currently not
302 supported. Matching is done case-insensitively.
303 EXPR may contain one leading path separator, in which case the
305 rest of the expression is matched against the start of the path.
306 Otherwise, the expression is matched against any part of the
307 path.
308 The --include option may be repeated in order allow files match‐
310 ing against one of multiple patterns. If --include is not used,
311 all files are processed.
312 -i --info
314 This is a convenience option to enable all actions that print
315 information about the installer.
316 Scrips should not rely on the output format with this option and
318 should instead enable the individual actions instead.
319 Currently this option enables --list-languages, --gog-game-id
321 and --show-password.
322 --language LANG
324 Extract only language-independent files and files for the given
325 language. By default all files are extracted.
326 To also skip language-independent files, combine this option
328 with --language-only.
329 --language-only
331 Only extract files that are language-specific.
332 This option can be combined with --language to only extract the
334 files of a specific language.
335 --license
337 Show license information.
338 -l, --list
340 List files contained in the installer but don't extract any‐
341 thing.
342 This action also enables the --list-sizes action unless either
344 --quiet or --silent is specified.
345 This option can be combined with --silent to print only the
347 names of the contained files (one per line) without additional
348 syntax that would make consumption by other scripts harder.
349 The --list action can be combined with --test, --extract,
351 --list-languages and/or --gog-game-id to display the names of
352 the files as they are extracted even with --silent.
353 --list-checksums
355 List checksums for files contained in the installer.
356 This option implies the --list action and can be combined with
358 the --list-sizes option to print both the size and checksum for
359 each file.
360 With --silent the file checksum will be printed at the start of
362 the line (but after the file size if enabled with the
363 --list-sizes option) followed by a space. Otherwise the checksum
364 is printed after the file name.
365 The checksum type can be one of Adler32, CRC32, MD5 or SHA-1 and
367 is printed in fron of the checksum hash followed by a space.
368 Adler32 and CRC32 checksums are printed as "0x" followed by the
369 32-bit hexadecimal value.
370 Different files in the same installer can have different check‐
372 sum types if GOG Galaxy file part reassembly is not disabled
373 using the --no-gog-galaxy option.
374 --list-languages
376 List languages supported by the installer.
377 This option can be combined with --silent to print only the
379 identifiers of the languages (one per line) followed by a space
380 and then the language name, without additional syntax that would
381 make consumption by other scripts harder.
382 The --list-languages action can be combined with --list, --test,
384 --extract and/or --gog-game-id to display the available lan‐
385 guages before doing anything else. If --silent and --list-lan‐
386 guages are combined with --list and/or --gog-game-id, the lan‐
387 guages list will be terminated with an empty line and will pre‐
388 cede both the game ID and files list.
389 --list-sizes
391 List uncompressed sizes for files contained in the installer.
392 This option implies the --list action and can be combined with
394 the --list-checksums option to print both the size and checksum
395 for each file.
396 With --silent the file size in bytes will be printed at the
398 start of the line followed by a space. Otherwise the size is
399 printed after the file name in a human-friendly format.
400 -L, --lowercase
402 Convert filenames stored in the installer to lower-case before
403 extracting.
404 -d, --output-dir DIR
406 Extract all files into the given directory. By default, innoex‐
407 tract will extract all files to the current directory.
408 If the specified directory does not exist, it will be created.
410 However, the parent directory must exist or extracting will
411 fail.
412 -P, --password PASSWORD
414 Specifies the password to decrypt encrypted files. The password
415 is assumed to be encoded as UTF-8 and converted the internal
416 encoding according used in the installer as needed.
417 Use the --password-file option to load the password from a file
419 or standard input instead. This option cannot be combined with
420 --password-file.
421 If this password does not match the checksum stored in the in‐
423 staller, encrypted files will be skipped but unencrypted files
424 will still be extracted. Use the --check-password option to
425 abort processing entirely if the password is incorrect.
426 --password-file FILE
428 Load a password form the specified file. Only the first line
429 excluding the terminating carriage return and/or line break is
430 used as the password. The password is assumed to be encoded as
431 UTF-8 and converted the internal encoding according used in the
432 installer as needed.
433 If the special file name "-" is used, the password will be read
435 from standard input.
436 Use the --password option to specify the password on the com‐
438 mand-line instead. This option cannot be combined with --pass‐
439 word.
440 If this password does not match the checksum stored in the in‐
442 staller, encrypted files will be skipped but unencrypted files
443 will still be extracted. Use the --check-password option to
444 abort processing entirely if the password is incorrect.
445 -p, --progress[=ENABLE]
447 By default innoextract will try to detect if the terminal sup‐
448 ports shell escape codes and enable or disable progress bar out‐
449 put accordingly. Pass 1 or true to --progress to force progress
450 bar output. Pass 0 or false to never show a progress bar.
451 -q, --quiet
453 Less verbose output.
454 --show-password
456 Show checksum $c and salt $s used for the password $p check as
457 well as encoding of the password. The checksum is calculated
458 from the salt concatenated with the password:
459 $c = hash($s . $p)
461 With the --silent option, the checksum name and hash is printed
463 on one line seperated by a space followed by the salt encoded as
464 hex bytes and password encoding on separate lines.
465 Checksum types can be CRC32, MD5 or SHA-1 although CRC32 is not
467 used in installers with encryption.
468 Use the --password or --password-file option together with
470 --check-password to check if a password matches this checksum.
471 -s, --silent
473 Don't output anything except errors and warnings unless explic‐
474 itly requested and use a machine-readable output format.
475 This option can be combined with --list to print only the names
477 of the contained files (one per line) without additional syntax
478 that would make consumption by other scripts harder.
479 -t, --test
481 Test archive integrity but don't write any output files.
482 This option can be combined with --extract to abort on file
484 checksum errors.
485 -T, --timestamps TZ
487 Inno Setup installers can contain timestamps in both UTC and
488 'local' timezones.
489 The --timestamps option specifies what timezone should be used
491 to adjust these 'local' file times.
492 Valid values are those accepted by tzset in the TZ environment
494 variable, except with the direction of the time offset reversed:
495 both -T CET and -T GMT+1 will (when DST is in effect) give the
496 same result.
497 Besides timezones, two special values are accepted:
499 "none" Don't preserve file times for extracted files, both for
502 UTC and 'local' timestamps. The file times will be left
503 the way the OS set them when creating the output files.
504 "local" Use the system timezone for 'local' timestamps. This is
506 the normal Inno Setup behavior, and can be used together
507 with the TZ environment variable.
508 The default value for this option is UTC, causing innoextract to
510 not adjust 'local' file times. File times marked as UTC in the
511 Inno Setup file will never be adjusted no matter what --time‐
512 stamps is set to.
513 -v, --version
515 Print the innoextract version number and supported Inno Setup
516 versions.
517 If combined with the --silent option, only the version number is
519 printed. Otherwise, the output will contain the name (innoex‐
520 tract) followed by the version number on the first line, and,
521 unless the --quiet options is specified, the range of suuported
522 Inno Setup installer versions on the second line.
523 --no-warn-unused
525 By default, innoextract will print a warning if it encounters
526 .bin files that look like they could be part of the setup but
527 are not used. This option disables that warning.
528
530 Paths in Inno Setup installers can contain constants (variable or code
531 references) that are expanded at install time. innoextract expands all
532 such constants to their name and replaces unsafe characters with $.
533 For exmaple {app} is expanded to app while {code:Example} is expanded
534 to code$Example.
535 There is currently no way to configure this expansion except for dis‐
537 abling it with the --dump option.
538
540 0 Success
541 1 Syntax or usage error
543 2+ Broken or unsupported setup file, or input/output error
545
547 There is no support for extracting individual components and limited
548 support for filtering by name.
549 Included scripts and checks are not executed.
551 The mapping from Inno Setup constants like the application directory to
553 subdirectories is hard-coded.
554 Names for data slice/disk files in multi-file installers must follow
556 the standard naming scheme.
