I have a variant on that problem. I use a Mac 10.6.8 to control a remote Win7 PC with TeamViewer. It's worked wonderfully for many years. So today I do a regular "update" of the PC TeamViewer. That's easy. TeamViewer disconnects while it loads the update, and then restarts. I then command a link to the PC from my Mac, and I get an error message -- "Your partner uses a newer version of TeamViewer. You need to update TeamViewer to establish a connection." Um, OK. So I command an update for TeamViewer on my Mac, and I am told that "You're up-to-date! TeamViewer 8.0.20942 is currently the newest version available."
So I'm stuck. I have no connection, and no idea what I need to do to establish one. Am I supposed to understand that the latest Win update won't talk to the latest mac update??
Help!
