I'm trying to download Minecraft forge, and It gives me a .jar file. I accidently set it to open with Photoshop, so I set it to open with Java, but when I try to open it, it opens, then closes immediately. When I try to force it open by clicking, it opens into cmd. I have the latest version of Java, and I have redownloaded it countless times, reset my computer, and I'm lost. I tried to make a .bat file but either I did it wrong or it didn't work, does anyone have a way to fix this that isn't too complicated? Or if it is, someone with very limited knowledge on computers can follow?
