I tryed to uninstall the 7.1 Rt version in order to reinstall the 7.0 RT version on a PXI controler (8170 serie), but i've got an error number 12031 for a file (nibffrp.dll).
My controled has an OS wnnt and i made the new installation in two steps : first i created an uninstall disk, and then i created a start disk from MAX.
Best regards,
G Liagre
