I had uninstalled PDMWorks from my machine. Later, when i attempted to remove the vault from machine, it threw a "Conisio" dialog stating
1. "Could not delete view"
2. "Class not registered"
Fix was right there in registery. I removed following keys and that was it, i was all set .
1. HKEY_LOCAL_MACHINE\SOFTWARE\SolidWorks\Applications
2. HKEY_CURRENT_USER\SOFTWARE\SolidWorks\Applications
