Duuuude! Zero! I can't even begin to thank you enough for this fix. I am not an IT professional and I am a noob when it comes to fixing stuff. I cannot tell you just how many hours, and MONTHS, I have spent trying to fix this whole steam issue from just even working period on my laptop. Steam would start up but the game would not even start up. Then I found out through another posting on the web that it was a compatibility issue and that I could run it using "Compatibility Mode" Just today I found out through a steam support that they do not recommend running in "Compatibility Mode". (Arrrrrrrg!) Then in the update for today, that they "allegedly" fixed the issue? (Running Windows 7 Home Premium x64) In the beginning I had spent HOURS on the steam support site with no luck, because they sure did not make anything easy. :boxing:So I gave up. :ranger:Started again etc. Thennnn....lol.... after all of this, I could not run the "Big Picture" mode due to the compatibility error that steam gave. Really??? They suggested that I turn off the UAC setting to off. So I did that. Then I also found steam.exe files in the registry like you suggested in BOTH places. I deleted 3 instances. One in the Current Users and Two in the Local Machine. For some reason the Bold in this blog will not go away...lol...sorry.... I tried. Well anyway... thank you so VERY much for your help. I am going to credit you with this fix. It worked like a charm and I signed up just to thank you! Thanks -fryer
