Thanks for doing this. I had an installation from a couple of years ago that was a much bigger pain, so this is great to have.
I had one small problem during installation that I wanted to report just in case anyone else has the same issue. I've seen it mentioned in passing here and there but not set down in one place. So I hope this is helpful to someone.
I'm doing a brand new install to a clean directory, using the GOG installer. I'm running Windows 7. I accepted the default directory name "Freespace 2" but placed it in "D:\games\flightsims\Freespace 2". Everything but the GOG installer worked OK, but that part logged an InnoExtract error:

On a hunch I renamed my install directory to 'Freespace2' and tried again, and that worked fine. I'd think it would have been fine because of the quotes around the path, but I'm a Unix guy and not an expert on the windows shell. My setup must be unusual (maybe the extra path element?). I didn't test with an equally long path but no space, so maybe it's a length issue not a space issue; the install path is 32 characters without the hex junk and 64 with it, and things going wrong around powers of 2 make me nervous.
(watch, not the very next thread I read is going to be a huge blinking warning about this I somehow missed before.
