question about wisdec under 2K

looks like I answer my own question again

This right from a "readme"

If you currently have a problem with an Installshield script file you can use either use
NaTzGULs and SiraXs wisdec, which is easy to use but has problems with many install shield scripts,
or use isDcc which can handle most scripts but that one gives you "only" the source of the script
which can�t be used immediately. Only with the install shield compiler itself can those scripts be
compiled again. Often you need the right compiler version for your script version and even then it can
be tricky to compile it.

END C&P from "readme"

seems that only program that will de-compile the setup.ins is "InstallShield Decompiler v1.00 beta 15"

and i5comp is only file that attempts to extract CAB files ...

any other suggestions are very welcome Thanx
