Hello Terry,
Upgrade is recommended. If upgrade fails, when upgrade setup is launched, it may request you to close running Comparator Fast for Windows before continue. To close Comparator Fast, go to
Main menu> File and choose Exit (or right-click System Tray icon and choose Exit).
You may also upgrade downloading current installer from:
http://www.interdesigner.com/downloads.htmBefore install, must exit Comparator Fast (same instructions).
If you want to disable Check for Updates, just go to
Main Menu> Help> Check for update option, go to Settings tab and uncheck
Automatically check for update every 7 days.
Regards,
