Hi! I wanted to move my virtual machines from VMWare to parallels. XP worked fine. But after importing my W7 x64-machine, it's not possible to start any program and parallels tool installation. E.G. Firefox Start: Firefox: WerFault.exe - Applocation error The Exception Integer division by zero. (0xc0000094) occured in the application 0x76d947df. Click OK to terminate the program. Firefox: Werfault.exe The instruction at 0x76d94a12 referenced memory at 0x5886dd90. The Memory could not be written. Click OK to terminate the program. Parallels Tools Installation: Windows Installer: Werfault.exe - Application Error The instruction at 0x76d94a12 referenced memory at 0x5703e0a8. The Memory could not be written. Click OK to terminate the program. Adobe Reader Start: Adobe Reader: Werfault.exe - Application Error The instruction at 0x76d94a12 referenced memory at 0x58dee120. The Memory could not be written. Click OK to terminate the program. Any ideas? Thanks Manfred
