I have some problems with this example also. Plz check my topic "Issues about PerformanceCount er(Chapter 22)".
Referring ur issue, try one of two ways:
1) using [MachineName]\[ur login name] if ur count is the administrator, and run this installation on local machine;
2) set ServiceProcessInstaller.Account as LocalSystem;
I hope one of them can work, but u may still occur the problem which I mentioned in my topic. Good luck!
