Question

Performance counters are EVIL. Don’t use them.

if(PerformanceCounterCategory.Exists("ILoveYou")  ) // is true
{
    PerformanceCounterCategory.Delete("ILoveYou"); 
    //throws exception The **configuration registry** key is invalid
}

at System.Diagnostics.PerformanceCounterLib.RegisterFiles(String arg0, Boolean unregister)
at System.Diagnostics.PerformanceCounterLib.UnregisterCategory(String categoryName)
at System.Diagnostics.PerformanceCounterCategory.Delete(String categoryName)
at WindowsFormsApplication1.Program.SetupCategory()

All I found is this:
http://blogs.msdn.com/b/oanapl/archive/2009/04/24/fix-corrupted-performance-counters.aspx
(Using LODCTR /R)

and it doesn’t help. As I have no idea what file are they talking about. Anyone got any other ideas?

PS
I use Windows XP SP3 may this be the problem? I understand it is suppose to support performance counters fully unless I cancel the page file.

to make this clear my problemis that I’m unable to UNINSTALL my counters.

Answer 1

My company runs into problems with the performance counters getting corrupt regularly. If it is a problem with the actual counters being corrupt, you can check for corrupted Performance Counters by:

1. Going to start | run | perfmon
2. Click OK
3. Click on the add button on the toolbar in the right panel (“+” sign button)
4. Ensure that the proformance object drop down menu contains items and not just numbers

If the Counters are numbers or Blank:
