My Portal 2 refuses to start up due to this, it crashes at it's menuscreen when launching directly, and Steam wants to have steam service installed if I launch Portal 2 via the games library. (Vista or 7 Mode)
Earlier today, it suddenly worked, I had the whole wineprefix set to winxp. Then I whiped the prefix, cause of mirror's edge problems...
Same problem than Jonas Jelten for "Spec Ops : The Line" in Steam + Vista/win7. I have a pop-up window to install Steam Service with this message : "So that this version of Steam works perfectly on this Windows version, you must to install the composant Steam Service. The process of installation of the service requires administrator's rights.
If i continue, an other popup windows invit you to relaunch Steam. But, when you relaunch it and the game, Steam Service is not installed.
