So I downloaded the installer, and jumped the WinRAR hurdle, but now I can't run the .jar file. Whenever I do, it opens cmd for a split second and says "could not find or load main class file net.minecraft.client.Minecraft". I have tried running it with the regular Java Runtime Environment, but I also tried javaw.exe. If I run it with javaw, it doesn't even open at all. Any ideas?
EDIT: Fixed. Dumbass me just had to redownload the .jar and run it right then and there. Sorry for the trouble
