Updating Unattended Acceress

Updating Unattended Acceress

I accidentally emailed an old version of the ZA_Access.exe installer to a customer.  I tried uninstalling, then reinstalling the lastest version, then rebooting. It was still running the old version.  I also tried updating to the latest version by running c:\Program Files (x86)\ZohoMeeting\UnAttended\ZohoMeeting\ZA_Upgrader.exe  -- I received a UAC prompt, but it didn't appear to do anything else.

The old verison works, but what can I do to get the latest version working?

Thanks.
