Vista SP2

Problems installing Vista SP2, generally with an error code of 80004005?

Good luck searching the web for help with that. There are roughly 8 million opinions (and 36,700 hits on Google) as to what might cause this, as I found when trying to update a friend's computer, but so far, only one person has a working solution.

The short version? Open regedit, and if this key does not exist, create it with the default value:

HKLM\Software\Microsoft\Windows\CurrentVersion\SysHiper

Service Pack 2 installs fine once that key is in place. Only took a dozen or so tries to install, with countless configuration changes over the course of my last week (on vacation) before I found that particular forum post. You are welcome.

If the key already exists, well then, you're probably buggered.
