IR in Vista x64 fails to talk to the device

Hi, the current version of IR fails to talk to the JP1 device. The reason behind this is that Vista x64 requires a signed 64 bit .sys file in order for the sys file to be loaded. From what I can see, the gwiopm.sys is very x86 specific (uses undocumented APIs) and is also not signed. I don't own the USB interface, but the delport USB driver's .sys file also seems to be x86 specific and is unsigned.

Other than installing XP in a dual boot scenario, is their any other alternative?

I found a workaround in the use of creating a Vmware XP 32 bit client on the Vista 64 bit host. I was a bit concerned that the Vmware virtual computer wouldn't be capable of passing the parallel port commands through to the physical port on the host, but it did work.
