I am trying to carry out a NI self test programmatically by using the command DAQmxSelfTestDevice. Even though the chassis is recognized by NI MAX, I still get the error -201233 (Object specified could not be found in storage). Also in the NI Device monitor I cannot see the chassis, if that information is of any use.
I downloaded NI-DAQmx 18.5 from here https://www.ni.com/de-at/support/downloads/drivers/download.ni-daqmx.html#288283 and installed it on an offline PC (win 7 ultimate). I used the 18.5 version because the latest version made the program crash somehow and I know that it should work with 18.5.
On another PC (Win 10) everything works just fine.
I reinstalled everything, but to no avail.
