unable to start CF Builder 2

I have installed ColdFusionBuilder_2_WWEJ on a  Microsoft Windows Server 2008 R2 Enterprise 6.1 System. jre-7u7-windows-x64 and jre-7u7-windows-i586 are already installed. The Builder get startet on one terminal session, but on all other sessions pops this error: Can anyone Help please!
