Over the weekend, I trashed my Intel Centrino x86 (32-bit) for AMD Turion2 x64 (64-bit). When I tried to install Interactive Broker's TWS after installing the 64-bit Java, I get the error message that Java isn't installed. I haven't done it yet but I figure this should be resolved once I install the 32-bit version of Java. But then what's the point of running 32-bit app on a 64-bit machine? Isn't TWS 64-bit compatible yet?
