My home computer is running version 14 while my work computer upgraded to 15. When i try to connect, the work computer says it cannot connect because the home computer is running an older version and that it needs to upgrade. When i check for updates, it says there is no update available. So i removed Teamviewer 15 from my work computer and installed v14. It still gives me the same error, that the home computer is an older version and cannot connect. I have uninstalled v14 from the work computer and have installed v13, v12 and v11 and all of them say the same. I do not understand why all versions 14 and lower on the work computer will not connect to v14 on the home computer, and why the v14 on the home computer says there is no upgrade available.
