Flight Simulator X service pack/SIMS 3
I installed FSX and the program seemed to work fine untill I installed the recomended service pack. After that service pack installation an error msg appeared about unable to find a system 32 DLL file. My entire desktop was missing along with the taskbar icons.
Thanks to RESTORE I was able to recover and bring those ICONs back to the desktop and taskbar. Prior to the installation of FSX I had installed SIMS 3. My first attemep at installing SIMS3 failed with a errpr message stating my Direct X was not currrent. After updating to Direct X 11, SIMS3 and it's update worked fine with Windows7. Just to be on the safe side, I picked my restore point to before SIMS3 was installed.
