Hi! I ran into a problem this morning with a new Windows update (I am running Vista Home Premium), where the update failed. This has never happened before. My error code was 8007643, which it turns out is some sort of generic catch-all. The update pertained to Microsoft Security Essentials. Just for grins I updated MSE and it worked fine, so I rebooted and tried to install the update again. Same result. There was an optional update for Vista available, so I tried updating both, and the optional worked, but the MSE failed. I looked again for answers and did a recommended update of .net framework and msi. Rebooted again. Tried the update again. Same problem. I read a suggestion of uninstalling/re-installing MSE, and tried that. It took several reboots, as there were residual files in program files, and then I cleaned the registry. And now MSE won't install, giving me the same error code! Very frustrating. Having spent an entire day attempting to fix this, and not wanting to have an unprotected computer, I installed Avast, which installed successfully. My concern is that I still don't know what went wrong, and should I be worried, or just stick with my new anti-virus and be glad to done with the old? History tells me that a problem ignored is not a problem solved, however.
My computer specs:
Pentium ® Dual-Core CPU ES200 @ 2.50 GHz 2.50 GHz
Memory (RAM): 4.00 GB
System type: 32-bit Operating System
Any suggestions/help would be appreciated!
Thanks!
