I recently did an in place upgrade of my Server 2008 R2 Standard VM's to Server 2008 R2 Enterprise via
Dism /online /Set-Edition:ServerEnterprise /ProductKey:xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
as referenced here: In-place upgrade from Windows Server Standard to Enterprise or Datacenter
This went well except for now when I want to install SP1 I get the following errors in the CBS.log:

Unfortunately there doesn't appear to be any resources on how to fix the Components hive (it exists and has the same permissions as a machine where the install successfully starts). This happens with the standalone installer as well as the windows update installer.
update switching back to the KMS key allows me to install SP1. Remains to be seen if RDP will work (another issue that cropped up as a part of this)
