EZRound has a built-in mechanism for getting program updates.
From the HELP menu, select "Check for Updates"
IMPORTANT
If you are running an Internet firewall (as you should be), make sure that the firewall is set to ALWAYS ALLOW these files to access the Internet:
SetupEZRound.exe
wupdate.exe
EZRound.exe
One or more of these programs will need to access the Internet to obtain your program updates. No personal information is ever sent to the Internet server.
As an alternative (if you are paranoid), you may download full versions of the program from the download area at http://www.ezround.com
