Ok, so I'm trying to make minecraft forge work. I have it installed, but whenever I double click on it to open and set it up, it asks how I want to open the .jar file. I watched YouTube videos because I thought I did something wrong, but whenever they click on it, it opens like it should normally. I even made sure they were running Windows 8. I'm using a 64 bit version of windows 8 if it makes a difference. Could anyone help me with this problem?
