Apply License Files for Virtuoso Releases 5.x and above, on Windows
          - Retrieve your new Virtuoso license file (e.g., virtuoso.lic) from email or ODS briefcase.
 
 
- Place the new license file in the appropriate directory.
 
 
              - By default this is C:\Program Files\OpenLink Software\Virtuoso\bin, but you may have installed elsewhere.
 
 
- If in doubt, check all System and User Environment Variables ( System control panel >> Advanced tab >> Environment Variables) for an OPL_LICENSE_DIR.
 
 
- If a license file by the same name is already present in any directory included in this variable, rename the old file and save it until you're sure the new one works.
 
 
 
- Launch the Services or Component Services utility ( Start menu >> Control Panel >> Administrative Tools).
 
 
- Stop and restart the OpenLink License Manager service.
