MATLAB 2018a Task specified is invalid or does not exist after upgrading NIDAQ max

[guadalupe777]

Hello,

I was using a code in matlab 2018a and after an upgrade of National instruments the drivers of NIDAQ max are no longer recognized.

I have tried to remove the new versions and downgrade to NIDAQmax 17.1  that previously was working but I got the same error about the drivers:

In NIDAQ_Driver/CheckErrorStatus (line 85)
In NIDAQ_Driver/WriteAnalogOutVoltage (line 237)
In NIDAQ_Driver/WriteAnalogOutLine (line 198)
In NIDAQ_Driver/WriteAnalogOutAllLines (line 214)

I have tried to downgrade to older versions but I got the same error. Thanks for any clue

I don't think Matlab questions belong into the LabVIEW forum.

(Maybe you want to move your post to one of the NI hardware forums, for example)
