Hi, I can't run Ufo:aftershock on my Inspiron 640m (RAM:2Gb CPU:IntelCoreDuo2 VIDEO:Intel945GM) with Windows 7.
When I launch the game I get an assert_fatal error:
file:C:\workdir\libglview\core\BasicOglWnd.cpp line:203 wglChoosePixelFormatARB() failed!
I already tried to reinstall, patch 1.3, and play with Compatibility/Administrator stuff!

I would like if it's run "Badly"... It simply doesn't run!!! sigh! :(
I found that somebody fix a similar problem running the "Repair" option in the uninstall program... but the gog.com's one doesnt work! when i click on unins000.exe, it crash with an error code "0x800704b3" someting like "Network path syntax error" (sorry, i have Windows in Italian, so i think it's useless to post the exact error message :) )

Probably Windows 7 / starforce compatibility which is the culprit
I have the original running by applying the 1.2 patch
and then the 1.21 patch to fix Win7 compatibility
The 1.3 fan patch is optional, as I've just noticed it exists right now ;)
More info and patches here:

edit: none of this need apply to the gog version, considering, drm free. So starforce shouldn't cause problems on win7 in the gog version. In that case atleast upgrade your graphics driver.

For those with intel graphics card and that cannot run Ufo Aftershock: apparentely there is a workaround using linux and wine that allows to run Aftershock in Intel graphic cards.

So the limitation is windows specific and not from hardware...

Make sure your video drivers are up to date. That may fix your problem.
