Forge isnt installing correctly

[PeterHartman]

Hi Guys!

I really hope youre able to help me with this problem. I tried to install forge a couple times on the 1.11.2 version of mc and it always it installed correctly but theres no profile in my mc launcher and no jar in my versions folder. so i dont really know what could cause that problem but i tried to run it as administrator and normal but still no change. ive got the installer log file here so maybe someone can help me with this .

forge-1.11.2-13.20.0.2286-installer-win.exe.log

And ive already ran the vanilla version before i wanted to install forge. still no jar file in my directory and the game crashes when i try to start it. even when i make a new profile which should be done by forge itself
