Have done but no effect.

Have you restarted the machine (actual windows restart, not turning off and on again)?

What version of NVDA and Windows?

Have you tried running NVDA with add-ons disabled?

Also, I know it seems silly, but try the COM Registration Fix tool again. I know of at least one case where a user reported that it didn't fix a problem it should have during the first run, but did after being run again. In theory that shouldn't be true, but that's what he reported.
