Now I use Labwiev7.1.1. Purchasing new USB hardware requires to install the DAQmx8.9.5 in order to support this HW, but installing it from the Labwiev examples disappeared all the former existing DAQmx examples. I have already tried to remove the 7.2 driver, and thereafter remove the 8.9.5 driver, then reinstall it again, but it didn't help. What have I made wrong?
