This is my issue, and ubisoft support has no clue here. Game ran fine until i installed Patch 1.2. About 80 hours logged no issues, but now i get an application error on launch and cannot play at all. I need the 1.2 patch for some mods that i would like to install. Graphics card, intel intergrated hd handeles the game fine, temps never execed 50 C. 6 gigs in ram, windows 7 64 bit, intel core i5 procceser. Any ideas for a fix. Note that this is NOT a ctd issue but an application error.
