After the test TeamViewer12 with a license, I have uninstalled TV12. Now no one else can use the QuickSupport on my computer. Is there a clean uninstall tool?
Thank you for your post.
Have you deinstalled TeamViewer via Control Panel --> Programs and Features with checked Remove settings?
With this setting TeamViewer should be uninstalled cleanly without further action.
Do you get any notification or error message if you started Quick-Support on this computer?
Could you please make a screenshot from this message?
