Will our existing drivers work with LabVIEW 8.x?

[Roger H.]

We have drivers for some of our DAQ products that were developed in LabVIEW 6 or 7.

Is there any reason these drivers would not work with the latest versions of LabVIEW?

We ask because there seem to be some customers in Europe who believe our drivers do not work with LabVIEW 8.5, but we know there are users with LabVIEW 8.0 and 8.1 using the drivers without problems.

Any thoughts or suggestions, or are there any known issues with older drivers in LabVIEW 8.5?

Roger,

It is certainly within the realm of possibility.  NI makes changes between versions which could have an effect.  It is possible a bug has affected your driver.  It is alos very possible your customer doesn't understand how to properly use your driver or modified it during the updrage process and broke it.

Unfortunately, there is no way for you to tell except to have someone you can work with to upgrade the driver and confirm it works.

Hi Roger,

In general, the latest versions of LabVIEW will work with older versions of the DAQ drivers.   However, it is certainly possible that some of the older drivers could have some conflicts. 

How “old” are the driver versions that your customers are using?  Specifically, what version of the driver does your customer report seeing the errors with?  Is  the customer using the same operating system that the original program was written for?  Is the customer seeing problems upgrading the VIs from LabVIEW 6 or 7 to LabVIEW 8.5?

The suggestion to work with someone to try it out is excellent.   Posting the specific driver versions seeing the conflict, might also shed some light on the issue.
