vRanger GUI fails to start after seemingly successful upgrade from version 5.3.x to 5.4.
From the command prompt run the following to get details:
"X:\Program Files (x86)\Quest Software\vRanger\Service>Vizioncore.vRanger.Service.exe" DEBUG
For version 5.4:
vRanger Backup & Replication encountered an error during startup. The exact error message was : Failed to launch service because the database version did not match the version number stored in the database.
vRanger Backup & Replication encountered an error during startup. The exact error message was : Attempted to perform an unauthorized operation.
The database may have been in transitional state.
