Solution
This error occurs when one of the performance counter registrations used by Witness has become corrupt. These performance counters are stored in the registry and in certain situations can become corrupt. Its not clear why, but it is a recognised error state and Microsoft have a documented fix.
Solution
To resolve the problem, you need to run a command, either directly or through Windows command prompt:

- Esnure you have logged onto the PC as an administrator.

- Enter the following command: lodctr.exe /r
- Select return.
