Upgrades are failing

The last two times I 'updated' Musescore it failed. The update processed, and seemed to work properly, but when I opened the updated application the screen appeared briefly (about 2 seconds) and then closed. I uninstalled Musescore, went to the website and downloaded the current version, installed it, and that worked.

This is intended more as a report, since I have resolved my own problem.

For the record, Dell Computer, Windows 10, 64 bit version.
