No GUI to create ini-files yet, sorry.

But supplied marsinst.ini is well documented with a lot of examples.

Anybody still using such software?

Maybe, but it's almost like everything XP slipstream and setup related has become less relevant as XP has become less relevant to the "general public."

I am still fine using your software on windows 7. If possible, add icon and update options. if you can combine the update feature like Ketarin, it's perfect!
