Vista32 Business, JV16 1.7.0.398.
Running the Reg cleaner finds a large number of disused file extensions when the previous version found none. At least one of the extensions found is valid (.QBB Quickbooks backup).
After exiting JV16 I have a Windows error that JV16 has stopped working. This is a consistent error.
