Hi The above error is occurring and if I set the proxy settings manually i get other errors. There is no stack trace java.version=1.7.0_25java.vendor=Oracle CorporationBootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=en_AUCommand-line arguments: -os win32 -ws win32 -arch x86_64 -data @noDefault I have downloaded copies of the proxy.pac file and checked it. Downloaded and resinstalled the Studio It seems there is issues around how the tool is handling proxy details Any assistance appreciated Peter
