What is odd to me is that during installation, Chrome asked if it could run in the background and I said no this time. Disabling it could very well be the solution.
It loaded!!! My first thought is that the background stub may be the source of the problem because it is the only difference from the previous setup. I started up Thunderbird, selected a message with a link and clicked on it. They were all as setup previously checked and confirmed. Then I went back over the previous steps in this thread to make sure the settings were all proper. There was no option or dialog to 'set up google chrome browser to also run from the Start app metro window'. Once this was 'exited', Windows allowed the uninstall. Anyway, I could not uninstall Chrome until I exited this background app through the system tray. I do know that I allowed a stub to run in the background during the first installation. I'm not even familiar with how to setup Chrome browser for the 'modern' or 'Metro' interface. default value = true ( no change needed)
