Aldelo Error: To many licenses used or backup states a station is logged in

Posted on

Upon launching Aldelo, you receive an error stating there are more computers connected to the database than are licensed or if you try to perform a backup it states a station is logged in.

This usually occurs if Aldelo was not properly shut down or was left running in another Windows account or you have too many stations exceeding your license count.

To remedy this:

  1. Open Aldelo
  2. Goto the Backend
  3. On the Top menu click Activities
  4. Click “Monitor client connections
  5. You will see a list of stations currently connected to the database.
  6. Shutdown any running Aldelo stations
  7. Click Done

Aldelo should start normally on all stations provided you have not again exceeded your license count and the backup should work properly.

Call Vanguard Systems if you need additional help.
