You will need to be able to log into ACT using the Administrator to be able to change the following preference.
Select Tools from the top menu within ACT and go down to preferences. With the Preferences Tab open go to the Startup Tab (Second last)
On this Tab you will find your log on settings, there is a check box option to set ACT to Automatically check for updates every X amount of days. Tick the checkbox and select apply.
If you are not the administrator user, log out of ACT and then back in under your user.
If you are running a shared ACT database with multiple users, please ensure you select this options for all machines, so that you will be running the same version of ACT.
