Cannot run DX11, Win7, button messed up: Fix: Vista compatibility mode was turned on

[srad]

Cannot run the game (demo ) in DX11 mode. The option is greyed out and tells something about "service pack 2 or greater" - see screenshot.

Notebook
Windows 7 64bit
ATI HD 5650 (Driver version 10.8 - seems to be the latest for notebooks)


Message:


Other games are running fine in DX11. Any suggestions?

Please look, if not maybe compatibilty mode for Windows Vista has been accidentially activated for civ5.

Problem solved: "Windows Vista" was checked on the steam.exe

Thank you!
