Quick Scan in CIS 6.2

When I click the SCAN button in the CIS interface, and then QUICK SCAN, it shows an effect of being pressed and depressed, but nothing happens. What gives?

On my PC, Quick scan is launched after pressing this sequence.

Ok, could be a bug related to updating from 5.x.

Did you merely do an “over the top” install? If so thats your problem. Should have uninstalled 5.xx completely first. Then install 6.2

Please try reinstalling by following the advice I give in this post.
