After downloading and installing the 7.6 Upgrade for Servicedesk, while attempting to login to the Processmanager portal, the following error popped up
Server Error in '/ProcessManager' Application.
Runtime Error: Description: An Exception occured while processing your request.
After changing the Processmanager’s Web.config file setting for CustomErrors to off, I saw the error listed below:
Server Error in '/ProcessManager' Application.
Could not load file or assembly ‘Symantec.Servicedesk.Cm.Core, version = 7.6.0.142, Culture=neutral, PublicKeyToken=null’ or one of its dependencies. The system cannot find the file specified.
When upgrading a Servicedesk system, the upgrade process requires all of the Servicedesk core dll files to be installed to upgrade correctly. The Symantec.ServiceDesk.Cm.Core.dll file was missing from the …\Program Files\Symantec\Workflow\Shared\customlib folder
A 7.6 version of the Symantec.ServiceDesk.Cm.Core.dll was provided, and copied to the correct folder. Afterwards, the upgrade installation completed successfully.
