Description
- When running Creo or Windchill Workgroup Manager (MCAD or ECAD) connected to Windchill environments on client workstations running McAfee Anti-virus or other virus scan tools, you may observe the following symptoms:
- The Windchill Workgroup Manager fails to launch after having launched successfully at first time, following installation and may show error:
Unable to connect to Windchill Workgroup Manager. If more than one instance of the authoring application is running, the new one will run disconnected.- Windchill Workgroup Manager shows error on Startup:
Actions Delete/Rename/Move Folder/File are not allowed in Windchill File System. Perform these actions in Windchill Server.- Save to Workspace from the CAD Application fails with error:
<Cache>PTC Places/Workspace/xxx.prt -File not found- Retrieval of a SolidWorks CAD Documents fails with error message on Open in SolidWorks:
C:\USERS\PTC Places\<cadname>.SLDPRT does not existFailed to open in SolidWorks 2018 XXX.SLDPRT. Failed to establish connection with SolidWorks 2018. Try launching SolidWorks 2018 manually for troubleshooting- Launching Workgroup Manager starts uwgm_client.exe however creoagent.exe is killed within a second,an and error message
"Invalid Server Location"is displayed after long time after registering the server - Unable to work with AutoCAD integrated with Windchill Workgroup Manager due to error -

- The PTC WFS Controller service is started but the Commonspace and Workspace are locations are not accessible through the Windchill File System
- The uwgm_client.exe process is running but no UI is presented
- Launching Windchill Workgroup Manager results in the authoring program and uwgm_client.exe being hung indefinitely
- Reinitializing cache locations resolve the issue, but only temporarily
- Windchill is extremely slow when switching workspaces
- Creo and Windchill Workgroup Manager needs to read, write and delete files for any given Windchill PDM operation any time. Hence it needs exclusive access to function correctly. Any failure while working with cache file is treated as exception or operation failure and could lead to cache corruption meaning cache is not usable
- Solidworks takes more than an hour to retrieve files in a linked session when it should take 3-4 minutes when scanning/protecting the system with "CrowdStrike Endpoint Protection"
- Creo Parametric exits second time after starting while it work well when connected to Windchill with fatal error
- Running Windchill Workgroup Manager causes client machine to freeze and stops responding for various actions
- Publish job fails with error "Returned file does not exists"
- Worker Fails to start Windows Defender Service MsMpEng.exe scans the WorkerDaemon.exe, workerhelper.exe, workermonitor.exe, and Creo View Adapters installation folder
