TeamViewer 8.0.16642 stopped loading on my Win 7 Ultimate box at startup. I went to services.msc and stopped TeamViewer. I went to Control Panel, Uninstall a Program and uninstalled TeamViewer. It took a long time to uninstall. I ran CCleaner Registry and deleted the TeamViewer entries. I also ran Little Registry Cleaner and deleted the TeamViewer entries. I deleted the TeamViewer folder in Programs x86 folder and ran both reg cleaners again and rebooted. I was able to successfully reinstall TeamViewer 8.0.16642 again... but TeamViewer fails to load on startup. I was not upgrading TeamViewer when I reinstalled it. Any ideas on how to get TeamViewer to load on startup? I'm confused because it used to work VERY well for me. I'm not sure why it stopped working or why it won't start at reboot in the system tray.
