Hello,

Im trying to create a new device object but im running always into trouble with the vendors *.dll.

What I already did:

Using tmtool to check drivers: NI5690 VXIplug&play driver was found
Using midedit to create a Matlab instrument driver (I used and imported the previously found VXIplug&play driver)

The Instrument Driver shows up in tmtool as well and all the few functions are found:

Now, if Im trying to create a device object, I always receive an error:

obj = icdevice('ni5690.mdd', 'PXI28::9::INSTR')
Error using instrgate (line 20)
Failed to load shared library.
Error in icdevice>localLoadVXIPnPLibrary (line 534)
    errflag = instrgate('privateIviCLoadlibrary',driverName, binary, includeFile, includePath, visaIncludePath);
Error in icdevice>localCreateWithMatlabInstrumentDriver (line 779)
        driverFound = localLoadVXIPnPLibrary(vxiDriverFileName);
Error in icdevice (line 267)
                obj.jobject = localCreateWithMatlabInstrumentDriver(mdd, hwobj,optionstring);
Caused by:
    Error using loadlibrary
    There was an error loading the library "C:\Program Files\IVI Foundation\VISA\Win64\Bin\ni5690.dll"
    'C:\Program Files\IVI Foundation\VISA\Win64\Bin\ni5690.dll' has different architecture than the host.
