I searched this forum for anything relating to 80070002 but came up empty handed. Vista was driving me CRAZY last night as when I try to install SP1 x64 via either windows update or manual update I receive windows update error 80070002. I went to microsoft's page and did as they instructed, deleting the temp files in downloads and such, and this did not solve the problem. I also went through three pages of google search, and read thru each thread to see what everyone was doing to fix this problem, and none of the solutions posted worked. Some of the posts were old (From 07) so I was hoping I might find a solution here. Can anyone help me out or have any advice? Thanks in advance!
