Help! I am trying to launch up The forge 1.7.2 recommended build (1121) but it will not launch, I have a similar issue with 1.6.4 forge as well.
When I try to launch, It says something cannot be launched and here is what I get in the Game Output tab of the launcher:

Please help me with this, I have tried trying to transfer Forge files from another PC where it worked but problem persists. Any suggestions?
