Comctl32.ocx File Is Missing Or Invalid

What is comctl32.ocx?

Comctl32.ocx is a Visual Basic 6.0 runtime file, but it is optional. If you do not have it in your system, you could get the error being discussed here. It might be possible that the file is present in the system, but isn’t the correct version. Another possibility is that the file could have gone corrupt.

In either case, the solution is to register or re-register the file from elevated Command Prompt. Before anything else, open Control Panel >> System and check whether your system is using a 32-bit or 64-bit version of Windows.
