innounp, the Inno Setup Unpacker
innounp, the Inno Setup Unpacker
Version 0.35
Supports Inno Setup versions 2.0.8 through 5.3.11
Inno Setup is a popular program
for making software installations. Unfortunately, there is no official unpacker - the
only method of getting the files out of the self-extracting executable
is to run it. One piece of software that addresses this issue is Sergei
Wanin's InstallExplorer,
a plug-in for the FAR Manager that unpacks
several types of installations, including Inno Setup (IS). But since it is not updated in a
timely fashion, and so does not support the latest IS most of the time, this program was born.
The advantages over InstallExplorer are:
Innounp is open source and based on IS source. Therefore, it is more likely
to support future IS versions.
It recovers portions of the installation script (.iss file), including the registry
changes and the compiled Innerfuse/RemObjects Pascal Script, if available.
If you want to report a bug, request a feature, or discuss anything else related
to the program, please write to the forum.

Both the source and the executable packages are compressed with
WinRar. While the full-featured packer is shareware,
the UnRar utility that can only extract files is free. And there are lots of free
third-party programs that unpack rar just fine, e.g. 7-Zip.
As a bonus, a simple unpacker for Setup
Factory installations is available on the download page. It is ripped from
the SynCE project.
Usage
Innounp is a console application, and it uses command-line options to find out
what to do. For a more human-friendly interface utilizing FAR or Total Commander as
a front-end see the MultiArc section below. Windows Explorer fans:
nullz has made
some .reg scripts to add innounp into the right-click menu and Richard Santaella crafted a
graphical wrapper for innounp (get it on the download page).
innounp [command] [options] lt;setup.exe or setup.0 gt; [@filelist] [filemask ...]
Commands:
(no) display general installation info
-v verbosely list the files (with sizes and timestamps)
-x extract the files from the installation (to the current directory, also see -d)
-e extract files without paths
-t test files for integrity
Options:
-b batch (non-interactive) mode - will not prompt for password or disk changes
-q do not indicate progress while extracting
-m process internal embedded files (such as license and uninstall.exe)
-pPASS decrypt the installation with a password
-dDIR extract the files into DIR (can be absolute or relative path)
-cDIR specifies that DIR is the current directory in the installation
-n don't attempt to unpack new versions
-fFILE same as -p but reads the password from FILE
-a process all copies of duplicate files
-y assume Yes on all queries (e.g. overwrite files)
If an installation has setup.0 (it is made without using SetupLdr), run
innounp on setup.0 instead of setup.exe.
To extract all files from a specific directory, use dirname\*.*, not
just dirname.
By default all files are extracted to the current directory. Use -d to
override this behaviour. For example, -dUnpacked will create a directory named
Unpacked inside the current directory and put the extracted files there.
The -c option is a little more tricky to explain. Suppose you opened an installation
in a file manager and browsed to {app}\subdir\program.exe. Now if you copied
program.exe to another location, the entire directory tree ({app}\subdir\)
would be created and program.exe would be extracted there. -c notifies innounp
that you are only interested in paths from the current directory and below, so that your
file, program.exe, is extracted right where you intended to copy it, not several
directory levels deeper. Note that in order to avoid confusion, files must still be
specified by their full path names inside the installation.
Note that an installation can contain several identical files (possibly under different names). Inno Setup
stores only one copy of such files, and by default innounp will also unpack one file. If you want to have
all files that could ever be installed anywhere, regardless of how many identical files this may get you,
-a option will do it.
If -m is specified, the file listing includes embedded\CompiledCode.bin
which is the code made by the RemObjects Pascal Script compiler. It is possible to disassemble
it using the ifps3_disasm.rar package on the download page. The result is not very
readable though since it uses the basic 'disassembler' from IFPS3. Anyone wants to write a
decompiler?
How to report bugs
OK, I know innounp is far from being perfect, but it is my intention to make
the program usable. User feedback is a great way to achieve this. Here's what you should
do if you find a bug and want it fixed.
Tell me what's wrong with innounp. If you encountered incorrect behaviour,
say what you think it should do and what it actually does. If it crashed or gave
an error message, say what did that - innounp, Windows, FAR, etc, and include
the details.
Describe the exact steps necessary to reproduce the bug. Say what are the
preconditions. Is the bug specific to some system settings? To a setup file you
have? (include the problem part of the installation script or a link to the compiled
setup, if it is small enough) To an IS version? To something else? Or does the
bug occur regardless of these things?
Once you have the bug report ready, post it to the forum. Remember, if I can't
reproduce the bug using the description you gave, the chances that it will be
fixed fall dramatically.
If the above guidelines were not obvious for you, I suggest that you read the
following articles.

0.16 (2005.04.30)
Supports IS up to 5.1.2-beta.
Innounp will try to unpack new versions of IS to handle the cases when the
binary format is compatible with one of the previous versions. Use -n
to disable this attempt.
0.15 (2005.03.08)
Supports IS up to 5.1.0-beta.
The old bug that prevented innounp from working properly with {reg:...} constants and
the like has got another fix.
Preliminary support for the 64-bit extensions that appeared in IS 5.1.0.
0.14 (2004.10.14)
Supports IS up to 5.0.4-beta.
It is now possible to specify the destination directory to extract files into using
the -d option. This directory will be created if necessary.
New option -c specifies the current directory inside an installation and
prevents the creation of the upper-level directories. MultiArc settings are updated
accordingly.
The old -c command is removed. To get the compiled Pascal script, use
-m and extract it like a normal file.
0.13 (2004.08.26)
Supports IS up to 5.0.3-beta.
Supports the Components and Tasks sections.
0.12 (2004.07.28)
Supports IS up to 5.0.0-beta.
Improved processing of big installations with many files.
Innounp now supports a certain level of user interaction - it prompts the user
for password and disk changes as necessary. To switch this functionality off (e.g. in
batch mode), use the -b option.
If no command is specified, innounp displays a brief summary of the specified
installation. The old -i command is removed. To get the setup script, extract it
like a normal file.
0.11 (2004.05.04)
Supports IS 4.2.2.
Supports ArcFour encryption. Use the -p switch to specify a password
if files are encrypted
0.10 (2004.04.26)
Fixed (again): filenames containing invalid characters could not be specified
on the command line or in a list file.
0.09 (2004.04.22)
Fixed (again): invalid characters in filenames (such as ':' and '|') made innounp crash.
Updated TC MultiArc settings.
0.08 (2004.04.14)
Added support for IS versions up to 4.2.1.
Added MultiArc settings for Total Commander (thanks to Gnozal).
Fixed a bug in MultiArc settings that prevented shells from displaying file
dates and times (thanks to Maxim Ryazanov).
The reconstructed setup script (.iss) is now included together with the 'normal' files.
Using -m option it's possible to view/extract other internal files in the same way.
0.07 (2004.03.16)
Multiple files with the same name are not overwritten now, instead they are appended
with numbers.
-c command extracts the compiled Innerfuse Pascal Script code to a file.
It can then be 'disassembled' with a separate tool. Get one on the download page.
The output of -i command now looks more like .iss script.
More data is included.
0.06 (2004.03.11)
Added support for IS versions 3.0.0 - 4.0.0.
Supports installations that were not packaged into a single exe using SetupLdr (these
can be identified by the presence of setup.0 which is appended to
setup.exe in packaged installations).
-i command displays registry changes made by an installation.
Supports (displays and reads from filelists) filenames with national
characters (single-byte character encodings only, Unicode/MBCS was not tested). The correct
code page must be set in Windows for this function to work properly.
[fix] File dates and times were not set during extraction.
0.05 (2004.03.09)
Improved batch processing. Now it's possible to browse and extract IS installations
in FAR using the supplied settings for the standard MultiArc plug-in.
Removed isbunzip.dll. Bzip2 library is linked statically.
0.04 (2004.02.27)
Initial release. Supports IS versions 4.0.1 - 4.1.8.
MultiArc settings
Unless you are a die-hard fan of command line, you may like the idea of working
with IS installations like with conventional archives in a file manager. Right now
two programs support this: FAR and Total Commander. Below are the instructions
how to integrate innounp into each.
FAR
Copy innounp.exe to a directory in your PATH and edit your
FAR\Plugins\MultiArc\Formats\Custom.ini file. There are two alternate
settings differing in several aspects and each having its own pros and cons. Try
the recommended setting first, if it does not work well for you, try the other
setting or even combine them.
Co-operation with InstallExplorer
If you have InstallExplorer installed (or another plug-in that handles IS,
but you will need to adjust the settings accordingly), you might want to let it
process all the other types of installations but keep IS installations for innounp.
FAR does not provide a means of customizing the plug-in call order; however, an
empirical study has shown that it loads plug-ins and applies them to files in
lexical order. So the solution is to rename InstallExplorer's dll file from 6InstExpl.dll
to e.g. zInstExpl.dll (and restart FAR).

Configuration made up by Gnozal and Maxwish and posted on
TC forum. Change the path below
to where you have innounp installed and add this to your MultiArc.ini. Note that
MultiArc is not included in the default TC installation, instead it is available as a
separate download from Siarzhuk Zharski's web site.
