Explaination: I am currently trying to run Forge with recommended version for MC 1.10.2. There are no mods added yet. I checked all the "quick fixes" available on here & across the internet but have had no luck yet. I am running it with Java 8u111. Using latest version of MultiMC launcher. The instance was ran before Forge was installed. The game crashes in its very start-up stage, before the window ever comes up. This is the same report I get each & every time I try to start up (I've tried numerous) and it never works.

[glow=red,2,300]Thank you so much for all your brain juices being used up to help me out with this in advanced![/glow] Your donations will not be lost in vain! 

I deleted the old instance, made a fresh vanilla instance, & attempted to use the Forge installer for 1.10.2 but it doesn't recognize the version or something. The problem I have with the installer is it keeps saying it can't find the minecraft profile for the version & that I need to launch Minecraft when I already launched that instance before attempting to install Forge. So now I am attempting to install in the old-fashioned way. Just figured I would make note of this issue for the Forge team.

That makes sense.  I haven't been able to install Forge manually yet on a count of life being busy. but will let you know the outcome when I'm able to.
