Is 32 bit Xilinx ISE Webpack compatible with 64 bit ChipScope Pro? ISE isn't seeing it when I try to add new source.

Is 32 bit Xilinx ISE Webpack compatible with 64 bit ChipScope Pro? ISE isn't seeing it when I try to add new source. I originally had the 32 bit ChipScope installed. ISE could see that and I was able to add a Chipscope module to my project. I uninstalled the 32 bit chipscope and installed the 64 bit version, ISE cannot see it now. Any idea what's going on? Thanks, Dale
