Hi,

If you encounter this error, please try the following and see.

Close Ansys completely.

Open My Computer.

Navigate to the address bar and type %appdata%, then press enter.

Locate the folder named Ansys and rename it to Ansys.bak.

Launch Workbench again; a new Ansys folder will be created automatically.

Retry the operation that led to the issue.

If the problem is resolved, it is safe to delete the Ansys.bak folder.
