I had QV10 Personal working OK on Vista.
I uninstalled it and installed QV11 R2.
Won't start - the Windows "QlikView 11.0 SR2 has stopped working" message.
Event log says:
Faulting application Qv.exe, version 11.0.11426.0, time stamp 0x509bc464, faulting module ntdll.dll, version 6.0.6002.18541, time stamp 0x4ec3e3d5, exception code 0xc0000374, fault offset 0x000b06b7, process id 0x1068, application start time 0x01cdccb2b6443e9e.
