JabRef 5.1-PullRequest6455.373--2020-05-10--23ed9f8
Windows 10 10.0 amd64
Java 14.0.1

I have the above snapshot installed. Earlier today I downloaded the latest one (JabRef-5.1.msi last modified 2020-05-12 07:54) and tried to install it. As soon as the "Welcome to the JabRef Setup Wizard" shows up, a message pops up telling me that

A higher version of JabRef is already installed. Downgrades disabled. Setup will now exit.

Sorry if this has already been addressed, but would I need to uninstall the previous snapshot before installing a later one?
