Unable to install SP1 windows 7 home premium 64bit. error 800B0100
Hello, I am having an issue getting windows 7 service pack 1 to install (windows6.1-KB976932-X64.exe).
I get error code TRUST_E_NOSIGNATURE(0x800b0100). These are troubleshooting steps i have already attempted. I had antivirus and firewall disabled during this whole process.
1.First i attempted to use the microsoft fixit tool located here Troubleshoot problems with installing updates - Windows Help
2.Ran a Sfc scannow test on command promt (no errors found)
3.Ran a diskchk on the harddrive which my windows OS was located on (no errors)
4.Ran System Update readiness tool which completed (log is attached)
5.Added Windows6.1KB947821-v34-x64.msu to my %Windir%\Temp\CheckSUR \servicing\packages\ directory. Reran System update readiness tool (same missing manifests, mum, and cat file errors in log).
So basically the next step from what I read is to do a install repair or to manually copy in the missing manifest, mum and cat files. I would prefer to do that latter but i don't have another 64bit machine to get the files from. I dont know where i would attain these files.
