FATAL ERROR Unhandled Access Violation Reading 0x0000 Exception at 2a759eh

Hello,
After the update that I’ve made to my Windows 7 this is the error that I have every time when I want to AutoCAD. Until now I didn’t find a solution for this and I don’t want to reinstall AutoCAD. So is there an expert online that can help me please to fix this ? I have this error because of the update ?
Thanks !
