I have been trying to install Windows 7 SP1 for days, and keep getting the same error code... "Invalid Value for Registry. Error: REGDB_E_INVALIDVALUE (0x80040153)"
I did the online help, with now luck, I did the 'Troubleshooting problems installing a service pack for Windows 7', (the sytem readiness tool wont install either, the troubleshooter said it resolved a problem, but didn't, and I have Avast AV, and it won't let me shut it down even using task manager), unable to run Windows Update in Safemode and tried to download and install manually while in Safemode, but same error.
Here is what is in Event Viewer...
Installation Failure: Windows failed to install the following update with error 0x80070643: Windows 7 Service Pack 1 for x64-based Systems (KB976932).
There are also a lot of these in Event Viewer, before and after the Install Failure...
"Event 18213 DistributedCOM.
The launch and activation security descriptor for the COM Server application with APPID
is invalid. It contains Access Control Entries with permissions that are invalid. The requested action was therefore not performed. This security permission can be corrected using the Component Services administrative tool."
Not sure if that has anything to do with it, but it looks like a problem as well.
Any idea how I can fix the registry error, short of re-installing Windows 7?
