A while back I accidentally changed how I open java .jar files and set it to always open with. Now I have set it back to Java(TM) Platform SE Binary and .jar files like the optifine installer will not open or a file to start a server. Whenever I double click on them they will open up what looks like a command prompt which will immediately close upon opening. Nothing new opens up in task manager. Is there any way to fix this? Thanks!
