Upgrading from Windows XP

[Greg01]

We are trying to upgrade a test system which used a 32 bit Windows XP with an
NI-6534 digital IO card in LabWindows/CVI 2010 to a 64 bit Windows 7 machine.  
For compatibility to other systems we need to stay with LabWindows/CVI 2010.  I
tried to install NI-DAQ 7.5 (Traditional) but it complained about the 64 bit
OS.  What do I need to do here?
Thanks,
Greg

Use the 32bit version of Windows 7 instead. AFAIK there is no 64bit support in NI-DAQ 7.5 (Traditional).

That is not an option.  We will be upgrading to NIDAQmx also so we can use Windows 7 64 bit.

Another problem we have run into is the old system used the parallel ports to communicate with custom hardware.  Can this be done with LabWindows 2010 and Windows 7 64 bit?

This can be another problem: the low level support driver is not supported on 64-bit systems, so if you are using low-level function to access the port like inp or outp (or other functions that imply to #include lowlvlio.h in your code) you cannot run your program on 64-bit systems. And, to run on 32-bit systems you will need admin privileges.
