Have tried using Windows Update and all three troubleshooting options i.e.
1. Run Windows Update Troubleshooting tool
2. Run System Update Readiness Tool
3. Turned off ALL security software (scarey)
In each case installation runs to 24% then reports failure with error code 800736B3
Have downloaded windows6.1-KB976932-X64.exe and run same. Ran for 22 minutes c.70% complete then reports:
Installation was not successful
The referenced assembly is not installed on your system
Error: ERROR_SXS_ASSEMBLY_NOT_FOUND(0x800736b3)
Any constructive suggestions much appreciated.
Thanks, John
Hello JohnSenior,
Thanks for your post. Let's try an InPlace Upgrade to correct any file corruption that may be preventing you from installing SP1.

The steps to perform an InPlace Upgrade are below:
How to perform a repair installation of Windows Vista, Windows Server 2008, Windows 7 or Windows Server 2008 R2. Performing a repair installation will
