cannot access national instruments hardware

Matlab 1018a and Matlab 1019a installed (both needed due to danger of your legendary version incompatibilities), both with DAQ Toolbox

NI-DAQmx drivers 17.1.1

Matlab 1010a: daq.getDevices() lists my 2 NI cards

Matlab 1019a: daq.getDevices() throws "... unable to detect NI hardware ..."

clicking the Addon Explorer Link in the error message, then "manage": Data Acquisition Toolbox for National Instruments NI-DAQmx Devices version 19.1.0 Install Date 22 November 2019

Why cannot I detect NI drivers and hardware in 2019a? How do I change that?
