InstallShield 12 Script decompiler ?

[QuakeGamer]

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:

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