I wonder if someone can tell me where, on a totally fresh install of WSS/MOSS 2007 on a 64bit machine, are the registry keys placed?
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\12.0
or is it:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Shared Tools\Web Server Extensions\12.0
(note the Wow6432Node bit in the second one.)
(I ask because my dev box recently got corrupted, and the problem seems to be that while SharePoint is looking for the WSS registry key under Wow6432Node, it only exists in the other registry location. I do not know what got corrupted -- whether it was the registry itself, or where SharePoint looks in the registry...)
