Windows Beta 7 Crash

[X-Kal]

I don't know if I'm doing something wrong here... but I can't seem to get the Windows Beta 7 to run properly. I've tried reinstalling it a few times -- deleting the whole folder & starting anew... but when I install it, it immediately crashes. It doesn't make a difference if I'm running 1.7.1 or not, it just crashes. (Incidentally, when 2.0b7 crashes, it takes 1.7.1 down with it too.

Might be skewed on your system.
