I have installed multiple versions of Forge. For some reason, any version of Forge that is 1.7.10 or does not run on the new Minecraft launcher. However, Forge 1.12.2 does work. I have not been able to test any versions in between even though I installed Forge 1.8.9 and 1.9.4, but I cannot see either of them. What's even worse is that when I press 'View crash report' nothing happens, and I have/had NO mods installed when making this report.
