Hi Dorra,
This is a multi server installation. The EPM addin is fine as the same version is used for the test and development systems. I am able to run reports and save data there.
Since the upgrade, we are getting this error. Further, when upgrading it, we got the error: "cannot open backup device '\\<servername>\OsoftSample\EnvironmentShell.db10' Operating System error 5 (Access is denied).
Sap Note: 1681663 said that this could be ignored. After installation, the admin client is working fine but the epm addin is throwing up this error.
