Please, just the programs that will not install or have major issues. If applicable, you can include why you think there's a specific cause.
NTREGOPT- installs with admin privileges, runs with at least 1 error, shows 1.88 billion entries ! (don't know about ERUNT)
Windows OneCare (as discussed)
Startup Control Panel (by Mike Lin) will install but will not open in Control Panel or Quick Launch, for me anyway.
