I have an old mac that I use to remotely access my desktop at home. I upgraded the desktop computer without knowing that the old laptop was running the newest version it was capable of. Now I'm unable to access the desktop from the old laptop. This is the message I get... "Version out-of-date: Update the remote TeamViewer - The remote TeamViewer is running an old version which is out of date. Therefore you cannot connect to this Version anymore. Your connection partner can update TeamViewer by clicking on "Help" - "Check for new version"." Is it possible to downgrade the desktop so that the versions are still the same?
