This error is occurring because QPS Server is installed with one user, but you are logged in as a different user while attempting to set up the File Repository.
Follow these steps to resolve this problem:
- Open the Services window and right click on QPS Server and click on Properties.
- Click on the Log-on tab and select This Account.
- Add the User information under which you are logged in on the QPS Server (Windows) machine.
If the problem persists, you can run QPS Server through the ServerStartup script (located in the installed folder for QPS Server).
