The only workaround I have found so far is as follows:
- Download TeamViewer Portable (http://www.teamviewer.com/download/version_5x/TeamViewerPortable.zip) and extract to a folder on your computer.
- Make a file association between TVC files and the TeamViewer Portable executable as seen below.
- Before trying to establish a connection by running a TVC file from Internet Explorer (Clicking TakeControl in GFI MAX RM):
a) Exist TeamViewer from the Taskbar.
b) Stop the TeamViewer services from the services control panel.
