I have identified two issues (problems.)

1. First is dealing with the installation. The Unknown Publisher is something you need to deal with for older applications.



Then of course, allowing the app Windows Defender permissions:


FrostWire's lack of an option to disable Update notifications always annoyed me; such a dangerous choice by the last developer of the project.



2. After installation, I found FrostWire was crashing immediately after startup. It turns out this is due to the earlier Java versions having a limit on their version number (thus the way FrostWire was designed.) Java now often uses more numbers to represent sub-versions of Java (java update version is greater than 256.) WireShare fixed this issue by replacing the icu utility but unfortunately for FrostWire, the only answer I can think of is to use an older java version. I'm using Java 8 which is showing the issue.

But only if this crashing at startup is applicable to you.


Where to get other versions of Java:
You should probably uninstall any present version of java. I recall in the past it was possible to have more than one version that might or might not cause issues.
(note: the larger JDK are developer versions, the smaller JRE versions are what most Windows users would use)
