*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

- Edit user permissions to the default save location so that the current user can save projects there.
