License Administrator After Upgrade 20.3.1 WILL NOT OPEN, SAGE NO ACESS "As Application is not Licensed"
Had same issue. Make sure everyone out of Sage. Go to task manager detail. Go to services tab. Right click on Sage.CRE300.HostingFramework.Service. Stop service for a minute or so. Then restart again. Run license administrator, update and close out. This worked for me.
