Upgrading Reader to Standard/ Pro.

Having an annoying issue while upgrading users from Acrobat Reader to Acrobat Standard/ Pro, depending on license.

By default we install Reader on everyone's machines. When a user requires a version of Acrobat with more features we assign them a license and go about upgrading it. 

Sometimes when I am upgrading Reader on Windows machines, I can go to 'tools' within the application and one of the listed tools will be 'Edit'. Clicking this prompts the application to check the user's account for a license, sees that they have a Standard/ Pro license and there's a popup saying Reader can't edit PDFs but since a license is possessed, it will upgrade to Standard/ Pro in the background. Perfect.

Other times (most of the time) this does not happen, because the 'tools' tab doesn't list all the features that better versions of Acrobat have, so there is nothing for me to click to prompt the upgrade. I then have to manually uninstall Reader, sift through the maze of results that shows up when I Google 'adobe acrobat standard download' and then try to navigate Adobe's terrible website that seems to move the download for Acrobat Standard every time I go to find it.

Please for the love of God can someone explain how I can 100% of the time prompt Reader to upgrade to Standard/ Pro without having to go through this arduous uninstall/reinstall process?

(And yes, the users are always signed into the correct Adobe account within the app, that is associated with the license).
