SYNOPSIS

innoextract [--extract] [--lowercase] [options] installers ...

innoextract --list [options] installers ...

innoextract --test [options] installers ...

DESCRIPTION

innoextract is a tool that can extract installer executables created by Inno Setup.

innoextract will extract files from installers specified on the command line.

To extract a multi-part installer with external data files, only the executable (.exe) file needs to be given as an argument to innoextract.

OPTIONS SUMMARY

Here is a short summary of the options available in innoextract. Please refer to the detailed documentation below for a complete description.

Generic options:

 -h --help               Show supported options
 -v --version            Print version information
    --license            Show license information

Actions:

 -t --test               Only verify checksums, don't write anything
 -e --extract            Extract files (default action)
 -l --list               Only list files, don't write anything

Modifiers:

    --dump               Dump contents without converting filenames
 -L --lowercase          Convert extracted filenames to lower-case
    --language LANG      Extract files for the given language
 -T --timestamps TZ      Timezone for file times or "local" or "none"
 -d --output-dir DIR     Extract files into the given directory

Display options:

 -q --quiet              Output less information
 -s --silent             Output only error/warning information
 -c --color[=ENABLE]     Enable/disable color output
 -p --progress[=ENABLE]  Enable/disable the progress bar

OPTIONS

-c, --color[=ENABLE]

By default innoextract will try to detect if the terminal supports shell escape codes and enable or disable color output accordingly. Pass 1 or true to --color to force color output. Pass 0 or false to never output color codes.

--dump

Don't convert Windows paths to UNIX paths and don't substitute variables in paths.

-e, --extract

Extract all files to the current directory. This action is enabled by default, unless either --list or --extract is specified. You may only specify one of --extract and --test.

-h, --help

Show a list of the supported options.

--language LANG

Extract only language-independent files and files for the given language. By default all files are extracted.

--license

Show license information.

-l, --list

List files contained in the installer but don't extract anything.

This option can be combined with --silent to print only the names of the contained files (one per line) without additional syntax that would make consumption by other scripts harder.

The --list option can be combined with --test or --extract to display the names of the files as they are extracted even with --silent.

-L, --lowercase

Convert filenames stored in the installer to lower-case before extracting.

-d, --output-dir DIR

Extract all files into the given directory. By default, innoextract will extract all files to the current directory.

If the specified directory does not exist, it will be created. However, the parent directory must exist or extracting will fail.

-p, --progress[=ENABLE]

By default innoextract will try to detect if the terminal supports shell escape codes and enable or disable progress bar output accordingly. Pass 1 or true to --progress to force progress bar output. Pass 0 or false to never show a progress bar.

-q, --quiet

Less verbose output.

-s, --silent

Don't output anything except errors and warnings unless explicitely requested.

This option can be combined with --list to print only the names of the contained files (one per line) without additional syntax that would make consumption by other scripts harder.

-t, --test

Test archive integrity but don't write any output files. You may only specify one of --extract and --test.

-T, --timestamps TZ

Inno Setup installers can contain timestamps in both UTC and 'local' timezones.

The --timestamps option specifies what timezone should be used to adjust these 'local' file times.

Valid values are those accepted by tzset in the TZ environment variable, except with the direction of the time offset reversed: both -T CET and -T GMT+1 will (when DST is in effect) give the same result.

Besides timezones, two special values are accepted:

  "none"    Don't preserve file times for extracted files, both for UTC and 'local' timestamps. The file times wil be left the way the OS set them when creating the output files.
  "local"  Use the system timezone for 'local' timestamps. This is the normal Inno Setup behavior, and can be used together with the TZ environment variable.

The default value for this option is UTC, causing innoextract to not adjust 'local' file times. File times marked as UTC in the Inno Setup file will never be adjusted no matter what --timestamps is set to.

-v, --version

Print the innoextract version number and supported Inno Setup versions.

If combined with the --silent option, only the version number is printed. Otherwise, the output will contain the name (innoextract) followed by the version number on the first line, and, unless the --quiet options is specified, the range of suuported Inno Setup installer versions on the second line.

EXIT VALUES

0

Success

1

Syntax or usage error

2+

Broken or unsupported setup file, or input/output error

LIMITATIONS

innoextract currently only supports extracting all the data. There is no support for extracting individual files or components and limited support for extracting language-specific files.

Included scripts and checks are not executed.

The mapping from Inno Setup variables like the application directory to subdirectories is hard-coded.

innoextract does not check if an installer includes multiple files with the same name and will continually overwrite the destination file when extracting.

Names for data slice/disk files in multi-file installers must follow the standard naming scheme.

Encrypted installers are not supported.
