I want to create a Setup to install my application. It as to be able to do the following:

• ask a question (maybe 2 radio buttons?) and, depending on the reply, copy one of 2 DLLs to the Windows directory and invoke regsvr to register the DLL
• write some registry keys

I would code my own program to do this, but I don't have enough knowledge of the different versions of Windows (XP, Vista, 7, etc) and 32/64 bit, registry layout, or permissions like UAC, etc

So, it seems to me that it would be easier to use a Setup generator which has been around for a while and already handles all of this stuff.

I went to my favorite site for free stuff and found this page. However, the programs mentioned there are either too simplistic or have too steep a learning curve for me.

Can anyone recommend a Goldilocks solution which does what I mentioned in those two bullet points while taking into account all Windows versions, 32/64 bit, non-admin accounts, etc?
