How to determine which version of Microsoft Operations Manager you are running

This article describes how to determine which version of Microsoft Operations Manager (MOM) you are running. In some cases, you may have to determine which version of the MOM client, the MOM database, the MOM Administrator Console, or the MOM Operator Console that you are running. You may have to determine what version you are running because these MOM components must be updated with the same version to function correctly.

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

1. Log on to the computer that is running the MOM Agent by using an account that has administrative permissions.
2. Click Start, click Run, type regedit in the Open box, and then click OK.
3. In Registry Editor, locate the following registry subkey:
   HKEY_LOCAL_MACHINE\Software\Mission Critical Software\Onepoint
