Operating system Windows Vista Ultimate SP2
IE9 version: 9.0.8112.16421IC (product ID: 03553-495-4913855-71770)
Tried stand alone versions of installers, same results - install failure, same error code - 80073712.
Tried installing Hotfix for Windows KB947821, installation failed.
Tried "Article 971058" Mr FixIt, did not correct the problem.
SFC scan produced no integrity problems.
No known viruse, malware or spyware (multitude of different scanners used).
Could someone intellegent from MS please tell me which services need to be turned back on or which settings to
adjust or which registry keys to fiddle with to get the updates to install. I also have had this problem for 2
years.
