c# - Cannot load Counter Name data because an invalid index -Exception

Question

I am using C# and WPF - Operating System is windows 7 Professional and Visual Studio 2012, SQL Server 2012.

I used Devexpress Grid in wpf. I want to bind it to database using ADO.Net Server mode. I selected "Items Source Wizard" Option to do this binding but it generated following Exception:

InvalidOperationException: Cannot load Counter Name data because an invalid index '' was read from the registry.

What does this exception mean?

Can you please help me to resolve this issue.

Thanks, Annie.

Just had that message related to Microsoft Dynamics CRM updates not installing and the marked answer for this post helped greatly:

Click Start, type cmd right click cmd.exe, and select Run as administrator. At the prompt, type lodctr /r and press ENTER.

Apparently, Windows keeps some counters cache in the registry at HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionPerflib09 Counter+Help. If this cache becomes corrupted (has blank lines), you get the above errors - and lodctr /r rebuilds that cache.
