Cause
This error occurs when PME is installed as a distributed system, and the database files on the database server are stored on a drive assigned a letter that doesn't also exist on the application server. For example, this can occur if the databases are stored on F: drive on the database server, and the PME application server doesn't have an F: drive mapped to it.

5. On the Sharing tab of the folder properties window, copy the Network Path:
