New New installation of Sage v2018 (New Server, nothing else installed other than SQL Express for future integration with TrueCommerce). Workstation runs just fine on the server, but when attempting to run on any local machines we get the error ""Unable to create a session object. The workstation may have been corrupted. Re-install Workstation Setup."" Created firewall inbound and outbound rules & I have followed KB 18982 to the letter. No UAC, Full read/write for 'everyone' installing as admin, using dns and ip. but no luck. Anyone have any other ideas? Runs in Mas90 mode just fine. So def something on the workstation.
