KB only applicable to if CU4 or later is installed.
You are prompted for the latest version of the Microsoft.SystemCenter.Library management pack when you try to edit a new management pack in the Authoring Console in Microsoft System Center Operations Manager 2007 R2 after you install Cumulative Update 4 (CU4) or later versions.
Root cause : This issue occurs because new management packs that are imported or created automatically in Operations Manager 2007 R2 after you install Cumulative Update 4 or later versions have a dependency on the latest version of the Microsoft.SystemCenter.Library management pack (The latest version of the Microsoft.SystemCenter.Library management pack may be version 6.1.7221.61 or a later version).
Resolution :To resolve this issue, download the latest version of the Microsoft.SystemCenter.Library management pack from the Microsoft Download Center, then extract the management pack and copy it to the following folder:%ProgramFiles%\System Center MP Authoring Console 2007
The next time that you use the Authoring Console to edit a new management pack, you will not be prompted for the Microsoft.SystemCenter.Library management pack.
