In Windows 10: Cannot uninstall nor update Musescore version 18.104.22.16878
1) I try to Update to a newer version - it fails to uninstall the existing one (refer to attached recording)
2) I try to uninstall Musescore using it own uninstaller - it fails to do so (refer to attached recording)
3) I look into the Windows 10 installed programs - Musescore does not appear in the list
But Musescore runs normally (which is the good news!)
There is no workaround, and I am stuck with this old version.
There is probably some registry kludge workaround, but I don't know where to find it.
