I have a Sage 300 2020 + PU1 running on Windows Server 2012 R2 Standard. When trying to print reports, I get the following error on the Server - Thus clients workstations are unable to print reports:

"Unable to cast COM object of type 'CrystalDecisions.ReportAppServer.Controllers.ReportSourceClass' to interface type CrystalDecisions.ReportAppServer.Controllers.!SCRReportSource'This operation failed because the QueryInterface call on the COM component for the interface IID '{98CDE168-C1BF-4179-BE4C-F2CFA7CB8398}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))."

How do I resolve this problem?
