Fixing 'Invalid Class' Error

Question: What should I do if I get an 'Invalid class' error when using Ceptah Bridge?

Answer: This happens because the Windows component called Windows Management Interface (WMI) is not working correctly on your computer. This issue is not related to Ceptah Bridge as such and, in theory, can cause problems with other applications.

To resolve this, you will need to fix the WMI repository. Search online for instructions on how to 'rebuild WMI repository' or contact your IT support team for assistance.
