Toolbox3After applying Cumulative Update 2 (CU2) for System Center Operations Manager 2007 R2, the OpsMgr shell may fail to open in environments with a code execution policy of “All Signed." The following errors are generated:

The following error occurred while loading the extended type data file:
Microsoft.EnterpriseManagement.OperationsManager.Client,
C:\Program Files\System  Center Operations Manager 2007\Microsoft.EnterpriseManagement.OperationsManager.ClientShell.Types.ps1xml : File skipped because of the following validation exception:
File C:\Program Files\System Center Operations Manager 2007\Microsoft.En terpriseManagement.OperationsManager.ClientShell.Types.ps1xml cannot be loaded.
The file C:\Program Files\System Center Operations Manager 2007\Microsoft.Enterp riseManagement.OperationsManager.ClientShell.Types.ps1xml is not digitally signed.
The script will not execute on the system. Please see "get-help about_signing " for more details...

There were errors in loading the format data file:
Microsoft.EnterpriseManagement.OperationsManager.Client, , C:\Program Files\Syst em Center Operations Manager 2007\Microsoft.EnterpriseManagement.OperationsManager.ClientShell.Format.ps1xml : File skipped because of the following validationexception:
File C:\Program Files\System Center Operations Manager 2007\Microsoft .EnterpriseManagement.OperationsManager.ClientShell.Format.ps1xml cannot be load ed.
The file C:\Program Files\System Center Operations Manager 2007\Microsoft.En terpriseManagement.OperationsManager.ClientShell.Format.ps1xml is not digitally signed.
The script will not execute on the system. Please see "get-help about_signing" for more details...”

Cause: The following files are not signed in CU2, thus causing this issue:

  • Microsoft.EnterpriseManagement.OperationsManager.ClientShell.Format.ps1xml
  • Microsoft.EnterpriseManagement.OperationsManager.ClientShell.Types.ps1xml
  • Microsoft.EnterpriseManagement.OperationsManager.ClientShell.Startup.ps1

We have confirmed this issue and a fix is scheduled to be released in a future update.

Workarounds:  To workaround this issue you can do one of the following:

- Change the PowerShell execution policy to allow these files to be executed.

or

- If your security requirements don’t allow the execution policy change, you can copy the above files 3 from the R2 RTM installation and then apply the workaround to fix the previous known issue as per the following link:
