I can install the Toolkit; however, the tools are not visibile and it does not link with MATLAB. Does there happen to be a special download for a 64 bit system? If there is I can't find one.
At this time, the only version that SIT is compatible is LabVIEW 32-bit. You can still run it on Windows 7 64-bit, but it must be the 32-bit version of LabVIEW in order to function properly.
