Re: APCC Pro version update

Hi Bryan,

That error message implies that some application was still using that DLL (maybe APCC was still running?).

Try rebooting and reinstalling before running anything else.

I get the same window as Sam, even after turning off Norton. I do not use MS security. After installing,
seems to work, but I did get the attached screenshot error.
