So I have 1.19 Forge, but I also want 1.8.9 Forge. When I run the installation for 1.8.9, it says "Successfully installed client profile forge 1.8.9-11.15.1.2318-1.8.9 into launcher". So I relaunch the Minecraft launcher and check my installations and the only forge there is 1.19. Do you guys have a fix for this. I've also deleted and redownloaded forge and it doesn't work. Edit: I looked at every forum and didn't find anything.
