Hi there Derek,
Couple of things to try here. In explorer go to c:\windows and find the
regedit.exe file and double click on it. If the file isn't there or doesn't
work try going to c:\windows\servicePackFiles\i386 and find it there.
Alternatively search for regedit.exe and it will find the files. Just double
click each of the executable and see if they work. Finally type into the run
box regedt32.exe -note the different syntax. Does that produce a registry
editor? Be aware that this is not the XP registry editor, but the one from
Win2000 and Windows NT. It is only safe to use this one in emergency
situations.
