Cannot Open .jar Files on windows 10

Q. Opening .Jar files by doubleclicking used to be a breeze, until I updated to Windows 10. Now when I double click a .jar file, it doesn’t open… Yes these are the same exact files that worked on windows 8… Is there a possible fix? Do I have to make IE my default browser?

Answer.

Reinstalling the program and the latest version of Java fixed this problem
