Hello, I have been trying to launch minecraft forge on my computer and it is not working. I have Java installed and updated and I am using Windows 10. I also have the Minecraft 1.6.2 and the same forge for it. Whenever I try to launch it from my files, it comes up with a screen for a fraction of a second and then disappears. I have tried uninstalling both things and re-installing as well as restarting my computer, but with no luck. I have also tried using the command, but whenever I do, I get "Error: Unable to access jarfile ". I would love some help, thank you.
