Please use Windows Registry Editor - regedit.exe. In the windows registry add to either HKLM or HKCU, under \Software\Macrobond Financial\AutomaticUpdates\Macrobond the following keys:
if set to 1 : if a new version is detected, the user is informed that there is a new version, but is not given the option to upgrade
if set to 0 : No checks are made at all
Please note that there’s no way to block Help > Check for update. Macrobond also does not provide a way to prevent user from going to https://redir.macrobond.com/go/installation and upgrade from there.
