My friend bought this Diskeeper 8.0 PRO and it can't installed. It said "Error 1920.Service Diskeeper (Diskeeper) failed to start. Verify that you have sufficient privileges to start system services."

I don't think the latter means much except that some users do in fact disable services and they typically shouldn't as it will interfere with alot of app installs. Has he disabled anything - using w2k here at the office - have him check and restore anything he disabled. Or maybe kill a few background apps - some time AV and even ZA interfere with installs.
If he hasn't, post back and I'll look around some more.
I think the error shows up in Norton and McAfee because it is a Windows Installer Error. I could be wrong but that is what it looks like to me from the screen shot you provided.
When you are in Services.msc, does the service give the same error? I did not see if you answered that. Did he have a previous version of Diskeepr installed? If he did and it was not removed, it could interfere with the install.
Have you tried to unistall the Application, Reboot and install again? If not, you could try that and see if anything changes.
You could try to create a new Administrator Account and install from thje new account. It is possible that a configuration option in the original user profile is causing the install to fail.
