Hi,
I downloaded the Windows installer and went through the standard installation procedure. After that, I tried to launch the game but it crashes. The console works. It shows "Initializing Sound", "Allocated 96 sources" as the last messages that appear prior to the crash. I see a window pop up next to the console and then it crashes. I've tried the normal launch and "vanilla renderer".
My system specs:
Windows 7 64-bit
8 GB RAM
Phenom II X6
ATI FireGL V7700 w/512 MB RAM
** EDIT **
Looks like the same problem as posted here: http://unvanquished.net/forum/viewtopic.php?f=6&t=1273
