• Vista - Cannot install SP2. Cannot install checksur.exe

  For Vista 64 SP2 fails to install on my machine (I have SP1). I get error 0 x 80040002 (no such interface - wish he told me what interface on which object but it is too much).

  After trying all sorts of things, I have downloaded and run installation for "analysis of system update tool." After a very long period the installation came back and said it was successful. But I can't find the checksur.exe anywhere on my machine.

  Everything I found was a new dir, d:\windows\checksur. This directory contains only 5 .cab files. I have not found the checksur.exe in any of them. Windows desktop search fails to find the file also (is not surprising given that I searched all c:\ and d:\ and came up empty.) Note: c:\ is my 64 bit XP and d:\ where my Vista 64 SP1.

  So, where is this tool or do I have to do now that I have installed these .cab files?
