Vista service pack 1 fails to install

[JeanT]

I have attempted to install Vista SP1 using download and also manually. All
attempts fail and I get error code 80070570. I'm attempting install on a
Dell Inspiron 1525 laptop.

I spent over 2 hours in a live chat with Microsoft tech support and they
couldn't install it either. Now someone else (the 3rd technician) is
supposed to call me tonight.

We unintalled PC-cillin, turned off all services. Nothing helped.

Any help on getting SP1 installed is appreciated.

Dell may have special instructions or a patch you need before upgrading to
SP1. Check with Dell and see.
