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

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_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\009 \ Counter+Help. If this cache becomes corrupted (has blank lines), you get the above errors – and lodctr /r rebuilds that cache.
