>I have been scared that if these mscomctl.ocx don't gell with the users machine all hell can break loose. I have s W2K machine and generally clients have W98 machines. I had a long time ago (maybe it was me as I was a newbie) distributed the mscomctl.ocx from W2K to a W98 machine and I ended up reinstalling W98 on that machine.

Maybe you're thinking of comctl32.dll? The Inno Setup documentation has a page about "unsafe files" that makes this point about comctl32.dll. It also mentions two other files to be careful with, but mscomctl.ocx is not one of them. AFAIK there are no issues concerning the distibution of mscomctl.ocx on different platforms, but if you have had experience to the contrary then you should seek more information before proceeding.

>Inno is great I am learning and appreciating it.

I agree, Inno Setup is a very nice tool.
