I recently had clean reinstall of Win7(2 months ago), updated WIN7 all the way to latest patches.
I have all redistributable C++ files (except 2005)
DX11 version is installed.
Uninstalled 1.2.16 completely (an removed user files completely).
Installed 1.5 beta (on disk other then Win7, disk D in my case).
Also I have a few games on my PC and all of them start without a problem.
I see this thread drifted from "crash on game start" issue to the "crash in mission", but neverthless here is my issue:
Unfortunately 1.5 beta gives me black screen (no sound ), changes resolution if I alt+tab while in black screen, and that is about it.
First time I installed 1.5 using its installer (a few hours after it became available) - resulted in black screen right after start.
Then I downloaded all files from your website (used torrent) and installed it again - black screen.
I looked at his thread and downloaded those 4 files and put them where adviced - black screen.
No idea what to do next, throwing white towel.
My PC is 2500 i5, Asus Motherboard P67, AMD R9290 GPU, sound onboard.
Catalyst 15.7 (15.20.1046-150622a-186188C driver) is installed.
