There is another solution, a rather awkward and kind of a PITA one, and that is to install a virtual machine such as VMWARE on your 64-bit host, then inside of that install your old 32-bit OS, then inside of that install your old version of CW. Set it up so that the host system resources are visible within the 32-bit OS, then you can run the old CW and communicate with your Freescale target hardware. I tried that once, and I thought it it just kind of buggered things up with regard to the target development process. Good luck!
