pcie communication with fpga

Hi

I am using cyclone 4 our own custom board which is working fine with 32 bit computer system using jungo driver but i dont have the jungo driver for 64-bit system so how can i test the pcie board with this 64-bit system.

I am using RW-Everything software in both the 32-bit and 64-bit system for to check the pcie communication but the rw-everything software is working fine with cyclone 4 starter board in both the systems. but our custom board is working fine with 32-bit system and not working in the 64-bit system.

what may be the reason....?

    RW everything is a cross platform application. So it does not really matter if you are working on a 32 bit or 64 bit platform. When you are using a Jungo driver, you should download the WinDriver for 64 bit platforms from the Jungo. Also make sure you set 64 bit alignment settings in the Jungo DMA APIs. These changes should work...
