I fixed the missing Windows Modules Installer according to Flavius's instructions ( http://www.vistax64.com/vista-general/218999-windows-modules-installer-missing.html ). Worked great with re-installing 'TrustedInstaller.exe' and everything is back to normal in the 'Services.msc' directory again.
However, now I am stuck with a '80070005' error code when trying to run Windows Updater.
I have already used Microsoft's 'Fix It' to reset Windows Update Components and to reset Security Settings to default settings. I have tried installing the 'subinacl.msi' and creating/running the 'reset.bat' file (apparantly this doesn't work on 64-bit systems). I even tried installing 'accesschk.exe' but the command promt appears then disappears in a milla-second.
I also tried running 'sfc /scannow' and continue to get the 'Windows Resource Protection could not start the repair service' error. I cannot do a Repair Install because I am using Vista Home Prem 64-bit SP2 and I do not have any Windows Install Disk.
Anybody got any suggestions?
