Hello again Jane42
Ok. Lets go back to square one, un-installing and re-installing the app. In your first reply/original inquiry, you said that you couldn't un-install and re-install the app for some reason. Have your tried a Forced Un-install (please note that a forced un-install is different than a regular un-install)? If not please follow the steps on this page https://appuals.com/how-to-uninstall-programs-on-windows-10-that-wont-uninstall/. I hope this helps!

Hello Jane42
I have done some searching through past Dropbox Forum questions and found a solution on how to fix this QT error. Go to, https://www.dropboxforum.com/t5/Dropbox-installs-integrations/Qt-platform-windows-failed-to-start/td-p/91545#M53129 and follow the instructions provided by the Accepted Solution. I hope this helps!
Thanks I found that string (which is 5 years old) but didn't find it helpful. I don't have any environemntal variables set and I can't find the AppData\Roaming\Dropbox\bin\plugins\platform file also mentioned. So I am hoping that after 5 years an up to date solution can be found
Hello again Jane42
Have you tried re-starting your computer? I don't think that this is a Dropbox error but instead a Windows error/problem. I found a thread on Microsoft that may be of help to you, https://answers.microsoft.com/en-us/windows/forum/windows_10-performance/qt-platform-plugin-issue-what-is-this-is-it-self/aa351756-eb09-491c-aebc-9058ca69c0a4. I hope this helps!
Yes I have restarted my PC a number of times and this problem has been occurring since 10 July. I am on the May 19 version of Windows 10 (1903) so the problem can't be a Windows update. It's frustrating that i can't uninstall and reinstall Dropbox to the latest version (and I don't know why) because that usually fixes the problem.
