reverser
first of all - my biggest thanks to you, sir. Sources open... Good!
secondly - I'd prefer not to have the tool, honestly, I don't need it. What I'd prefer to have is a METHODOLOGY of how to obtain the structure of the given inx file and how to decompile the higher versions inx files.
That's why I'm digging COM IS files now. That's why I'm playing with InstDev now.
BTW, nikolastela, the utility has been finished. It is better then Pietrek's one

Therefore I have to go through the same shit again. To persuade me I'm wrong, would you, please, run his utility against two files - IDriver.exe and IScript7.dll - these are main InstallShield files located in C:\Program Files\Common Files\InstallShield\Driver\7\Intel 32. Thanks in advance. If succesful - please, let me know!
