acrobat pro 2017 does not include a check for updates menu item

After installing Acrobat 2017 pro the help drop down menu does not include "check for updates" .

We are not sure if this means it is already updated all the way or if the update process is not available.

The computers are Windows 7 Pro 32 bit with 4GB of ram.

We have tried uninstalling and reinstalling but nothing seems to help.

Any guidance would be greatly appreciated.

Thanks,
