Since X-Designer is a 32 bit application it must be integrated with the 32 bit version of the XRT widgets. This does not affect X-Designer's generated code in any way. You can still build a 64 bit application from the generated code as long as you have the correct Makefile configured in the Makefile Options dialog and the 64 bit version of the XRT widgets. You can carry out the integration on a 64 bit machine, that is of no consequence. However you must perform the integration against the 32 bit version of the widgets.
