If your computer is connected to the internet, you can go to the Help - Check for updates. Check the box at the bottom to Check for Updates at Start up. Click OK. Each time there is a new update you will be notified when opening the program.
I am not certain if you are on a current Update Service Plan. To get the version 2017 to install, you must have a Trimble Ag login account. You can go to www.trimbleag.com. Click the link called Create Trimble ID. If you have had a previous CF Login from either the old website or from online ordering, this login should still work so this step can be eliminated. Then send an email to TABS_support@trimble.com requesting you would like to install the vs 2017 with same email address used in your login and a support technician can help you with the next steps to getting that version downloaded and installed.
