I can't seem to replicate this problem in here in my machine. Everything is working fine. Please download TeamViewer here: Link and then send me your TeamViewerID and Password so that I can help you troubleshoot this problem a little better.
It's not a huge thread or a problem to read the previous page, finding out that someone already had this very issue and it got solved.
DDS updated his trainer and you have to run it with admin rights.
Please delete your trainer, wipe/clean your cache/Windows temp folder, reboot your PC, download the latest trainer, run it with admin rights and try again.
