I have some issues with the installation of the currently recommendet Forge version "forge-1.11.2-18.104.22.1688" and need help.
I just downloaded the newest version of Minecraft and also updated Java. Then I opened the forge installation file and used the prescribed options.
After installing this Error message shows up and i cannot use Forge (see attached Picture).
Can someone help me with this problem?
Please download the .jar version of the installer (not the Installer-Win variant).
Open the folder containing the downloaded file in Windows Explorer.
Hold down shift and right-click an empty space, then select "Open command window here".
In the new window type java -Djava.net.preferIPv4Stack=true -jar [name of the installer], replacing [name of the installer] with the complete file name of the installer, including the .jar file extension. Then hit enter.
