Ooops. If you installed the free video-editor Kdenlive…
“before 10th July 2019, simply delete the installed files and folders manually”
This is because, if installed to a custom install folder rather than Program Files…
“the application Uninstaller was deleting all user data in the installation folder”
Yup, so the Uninstaller would delete your My Documents if that’s where it was located. Possibly even C:/, if installed on the root. Nasty.
But the uninstaller is obviously still screwy even in the latest version. I could not get the latest software to start, tried to uninstall, and was denied. Killing processes made no difference. Rebooting the PC made no difference. There are complaints on the forums about the same thing, and about how many inter-op processes its spawns even when not active. Eventually I had to manually delete all its folders and its AppData (two locations) and then clean the Registry to get rid of it.
What a pain. Stay well away from this software, whatever the reviewers may have said about it 18 months ago.
