                          ERROR - System Argument Exception When Running a Simulation

                          Authored by Aaron Schedlin December 8th, 2023 2828 views 0 likes KB2304010

                          ERROR

                          When running a simulation, you get the below error message:

                          Object must be a root directory (“C:\”) or a drive letter (“C”).
                          Details:
                          System.ArgumentException: Object must be a root directory (“C:\”) or a drive letter (“C”).
                          At System.IO.DriveInfo..ctor (String driveName)
                          At Ansys.Core.Persistence.ProjectSaveHandler.DoProjectSave()
                          …
                          Ansys.Core.Commands.CommandFailedException: Object must be a root directory (“C:\”) or a drive letter (“C”).

                          Software & Version

                          Workbench 2022R1

                          *This example was taken from this version but is not necessarily limited to this version.

                          Description/Cause

                          In this case, a new version of Ansys was installed and overwrote the default save location. The current user did not have permissions to save to the default save location.

                          *The cause(s) we identified in this documented instance may not be the only cause(s) for this error.

                          Solution

                          1. Correct the default save location to what it was set to prior. Tools>Preferences>Project Management
                          2. Edit user permissions to the default save location so that the current user can save projects there.
