SP1 installation problems

[gunneradt]

I have various pcs/laptops and sp1 has installed fine on all but one.

It's an acer aspire desktop and I havent seen behaviour like this before - I was wondering if anyone can point me in the right direction.

On windows update it failes to configure right at the death (99%) - but worse than that it fails to revert properly leaving me with a system where all the programs won't launch (via desktop shortcuts or via explorer) - useless in effect - the only way to get the system back is via system restore from safe mode.

I did get it to install from the full SP1 download but the system on completion was exactly as described above and system restore was required again.

Struggling to work out what could be causing the conflict. I uninstalled nod32 prior to install to see if that helped but it didn't. The pc is approx 6 months old and has been perfect until now. It's 64 bit, 4gb ram, nvidia grahics card - really struggling to work out whats happening.

cheers for any help

Have you read this?

Steps to follow before you install Windows 7 Service Pack 1 from the Microsoft Download Center

Thanks for your reply

Im not using an integrated graphics device

I have the update mentioned and I certainly have no malware

As I said everything has been perfect till this. It's almost as if SP1 completely breaks windows.

Did you reset WU as mentioned in post #2?

I had missed that post - Ive done that now

I will re-try and sp1 update and report back

thanks for the help

well unfortunately that didn't solve the problem.

The only thing different I noticed was that the install got to 100% this time on the reboot before deciding that it had failed and was reversing changes.

However, as before, sp1 doesn't uninstall properly at all, breaks windows on reboot requiring a system restore from safe mode to get the workable system back

very confused.

Im guessing this must be some kind of driver conflict somewhere but ive no idea what

No help here but I feel your pain. I have Acer laptop with Home Premium 64-bit. Here is my experience:

I have kept my laptop updated but decided to give the sp1 a go. Sorry I did. My download was interrupted the first time I started. Now whenever I try to start again it sits at 0% and my hard drive light stays on constantly. I left it go that way for half an hour but was afraid I was going to fry my hard drive. Managed to do a restore and everything back to normal.
I would advise against this if you've kept your system updated.

UPDATE:

Well, I finally got it to work after deleting the files in \Windows\SoftwareDistribution folder. Still took over 2 hours on a laptop that had all the current updates. Long periods where it appeared it had stalled or locked up with constant hard drive light.
Not a pretty install and sad that the user has to take unusual actions to make it work.
