I'm having same problem as Colorado - post #1, I'm using older desktop computer Win 7.
Butel ARC536 PRO, worked fine until upgrade I did yesterday, visual control seems to function but not able to down/upload. Detect Scanner just does not work. Downloaded new version, 3 different times did install and even did repair function, still no go.
Pulled out old laptop using version 2.1, connected the same cable, everything worked perfectly?
Desktop still not working.
Open for suggestions.
