I'm working on a MapSource installer for Windows

I’m working on a MapSource installer for Windows as detailed in this blog post. Here’s a screenshot:

It would be useful to get some input about how such an installer should work, i.e. what features users want/don’t want etc. And if win32 users can peek into their registry to see if what the big proprietary map packages write their is consistent (or not) with how I think the registry format for MapSource works that would be a big help.

You’ve already looked at the NSIS installer source file that is provided with each combined map on http://garmin.na1400.info/routable.html?
