Windows Server 2008 R2 x64 and Symantec End Point Protection SBE not installing.

I had a Windows 2008 R2 x64 server that I was attempting to instal the Symantec Endpoint Manager on, but it would not instal, and the following message was left in the event log:

Symantec Endpoint Protection (SEP) Installation fails with the following error “Symantec Endpoint Protection has detected that there are pending system changes that require a reboot. Please reboot the system and rerun the installation.”

I rebooted the server and then tried to instal the Manger again, but the same error would appear.

I found that there was a registry entry that was giving me grief with the install, and here are the instructions that I used to fix the problem.

1.Navigate to:
2.Back up the registry key
3.Delete the registry key
4.Install the software without restarting the computer first (Restarting the computer may result in the registry key being placed back in the registry before installation.)
5.Restore the registry key from the backup location.
