Problem: When installing or patching WebPlus, you see the error 'Could not write value ThreadingModel to key' or 'Could not create key', followed by the name of a registry key.

This problem is caused by your install of Adobe Flash Player which has prevented WebPlus from writing some new entries to the registry.
