InstallShield 12 Script decompiler ?
 

Exist some new tool that can handle InstallShield 12 script files (setup.inx)? I can't process it with old tools (ISDGoBack, ISDHelper, SID ...)

A 'friend' contributed this to me recently. I will also be posting it to my site shortly but will make it available here. Feedback appreciated.

Regards,

CrackZ.

Thanks, that's what i need! It must be some private modification, because i don't hear about it ;-)

Summary: isDcc31 decrypt script - OK, but decompile only part of file and then exit as usually (no error, output only 150kb of 3,2mb listing). I finish it with sid (installshield 6/7 script decompiler v1.0 written by sn00pee). Maybe some bug that can be corrected. PM me for example. It will be good fix this nice tool :-)

I am the "Friend" who hacked away that version and indeed it is some private modification :)
I needed the tool for something so I wrote it.
Unfortunately I had very little samples to test it with so I am not surprised that it is crashing half-way.

DARKER, If you can drop me a pm, we can discuss how I can test your file and hopefully provide a fixed version.

Thanks to DARKER I have an updated version.
It seems that in some case one of the value I was relying on was 0 when it was supposed to be an offset telling me the end of the code segment.
Well in that case I treat the end of the file as the end of the code segment and it seems to do the trick.;)

Enjoys.
:D

please upload rapidshare :S

Here you go

This nice decompiler still works with .inx of v14 out of year 2008... :)
But ist there a tool for extracting .cab for installshield 2008 v14? :confused:

I can't find anything, so may be someone can help.

Hi,

i can create setup.inx.dec but unable to make any changes in unencrypted setup.inx with isdcc31? Any clues?

Limited patching avaible by this tool:


[sid] - installshield 6/7 script decompiler
v1.0 written by sn00pee

introduction
------------
sid is designed to decompile installshield .inx scripts created with
installshield 6 or 7. additionally it allows the user to take a few
changes to the code and patch the script.

features:
- decompiles every .inx script file
- automatically detects IS standard lib functions
- patch parts of the script
- easy to use program environment

recompile setup.inx
 

I decrypted the inx file with isdcc31 but when I tried to decompile with sid (sn00pee) it crashed.
Finally, I decompiled with nekosuki, I patched but I don't know how to recompile to setup.inx
Any idea, please.

As far as I know the *.inx should be "decompiled" with other programs. I will post it when I find it (it has been some time in my collection).

SID does not complete decompiling and crashes in my case. Any updates for SID ?

installshield, setup.inx
 

Did you try isd beta 16 ?

Thanks, does this decompiler even work on newer verisons?

@chronos
let it be your home work
try it and tell the community!

ther is a SID imporved version can decompile higher version installshield

Do you mean an update to this old (but gold) tool? If so, can you provide more details about it? TIA.

Can someone upload isDcc31 to somewhere else please?

here we go -

isDcc v3.1, (c) 1998 Andrew de Quincey
isDcc v2.00, (c) 2000 Mr. Smith
isDcc v2.10, (c) 2001 Mr. Smith
isDcc v3.10, (c) 2001 Mr Won't tell:)
Syntax : isDcc -u filename.inx //To Unscramble the script file
Syntax : isDcc -s filename.inx.dec //To Scramble the script file
Syntax : isDcc filename.inx.dec //To desassemble the script file

Is there any way to add the modified files to *.cab package ?
ISCAB.exe is discontinued and doesn't work with newer versions :-(

repack it

with advanced installer

capture before and after and generate msi NEW installer

no other solution no one have updated version of that tool, anyway was useless.

Tool is 7 years old. Now there are better tools to unpack installers. That tool was very good in its time.

Thanks Guys;

I will try with AI .

Rasmus - can you recommend something ?

PS. I have setup & *.cab - not *.msi
That's why I want to update *.cab (file extract is possible, but how to exchange a modified file ?)

I'm sorry for resurrecting this old topic. I am currently trying to decompile some custom actions in a msi installer. With ORCA, I see that the custom action is located in issetup.dll.

Am I right to assume that the function that is called from the installer actually then resides in setup.inx? I am trying to decompile with some older SID version, but can't find any other tools...

The setup.inx may contain the called functions.
Can you share a copy of the "setup.inx" file?

Unfortunately I cannot the share the .inx file. But I succeeded using https://github.com/darknesswind/IsDcc.git and fixing its compilation errors. With that, i was able to see which DLL-Functions where called from the script code.

Fixes were:

https://github.com/darknesswind/IsDcc/blob/master/common.h#L29

Changing that to TYPE_UNDEF5, instead of TYPE_AUTOSTRING - if I recall correctly.
