The NI-Digital Pattern Driver 17.0.3 patch resolves the issue outlined in the table below for the NI-Digital Pattern driver 17.0. NI highly recommends this patch for all NI-Digital 17.0 installations and PXIe-6570 Digital Pattern Instruments.
The patch is available through NI Update Service or you can download directly through the Drivers and Updates page linked below.
The NI-Digital driver is not installing policy files that redirect between major/minor versions when using the .NET API. The lack of policy files means that code built against an older version of NI-Digital will have to be recompiled before it can be used on a system that only has the newer version.
