After lots of mail back and forth with TV helpdesk and trying their several proposed solutions, it finally works. I now use TV12-0-83-369 on Win8.1 and i'm happy!
Hang on with their help crew!
I downloaded the full TeamViewer appy and installed it on my Win7 PC. I pinned a start button to the task bar and when I touch it, there is a flash and then no further evidence that it is ready and no window showing its ready. When I login to TeamViewer.com, I get a page with a list of my computers i have loaded TeamViewer in to but there is no button or action i can find to begin looking at the remote laptop from my PC. One bit of help from *someone* seems to indicate I may have a firewall problem but I dont know why that would keep me from seeing another computer inside my router network ??? Any help, anyone?
I found only one way to clear this problem occured few days ago...
I have unistall Version 13 and reinstalled old version 11 now every thing work fine.
DO NOT UPDATE SOMETHING WOIRKING
