    Running the Core Server Activation tool, clicking on Activate, results in the error 'There was an error activating this Core'. Clicking on Licenses will show a blank screen.

    Solution

     

    1. Run Core Server Activation as administrator. ( ...\Program Files\LANDesk\ManagementSuite\LANDesk.ManagementSuite.Licensing.ActivateCore.exe)
    2. Check available free space.

     

    The temp folder of the user activating the core was cleaned up (C:\Users\USERNAME\AppData\Local\Temp).

     

    In Windows Server, the actual environment variable points to a submap of this Temp folder. Usually, this is folder 1,2 or 3.

     

    You can check this by running a command prompt run "set'" This will show the values for %TEMP% and %TMP%.

    Note the subfolder and recreate it. Now you should be able to activate your Core again.
