Hi captainlaw, i have not tested yet. But you have to download the 64 bit jdk. In the TOS*.zip you have the file TalendOpenStudio-win32-x86_64.exe. May be you have to adjust the TalendOpenStudio-win32-x86_64.ini. We run the Commandline (TIS Studio) on a linux 64 bit server. There we have to add a special 64 bit parameter in the corresponding *.ini -XX:CompileCommand=exclude,org/eclipse/core/internal/dtree/DataTreeNode,forwardDeltaWith Try it and please give feedback.
The same TalendOpenStudio download Archive file is working for different OS : - For Windows platform (2000, Xp, Vista, 7) 32 bit or 64bit. You need to install the correct JVM if you like to run the Studio on a 32 or 64bit architecture and run the right execution file : TalendOpenStudio-win32-x86.exe or TalendOpenStudio-win32-x86_64.exe. - The same archive would work for Unix, Linux and MacOS machine in 32 or 64bit. Best regards;
