daq.getVendors() takes half of forever on R2015b, 32bit; createSession('nidaq') doesn't work...

• Installed MATLAB R2015b
• Installed NI-DAQmx 17.5
• daqregister('nidaq') as admin
• Downloaded and installed NI-DAQmx Support Package for MATLAB
• Re-started MATLAB

>> tic, daq.getVendors(), toc

ans = 

Data acquisition vendor 'National Instruments':

            ID: 'ni'
      FullName: 'National Instruments'
AdaptorVersion: '3.8 (R2015b)'
 DriverVersion: '17.0.0 NI-DAQmx'

Properties, Methods, Events

Additional data acquisition vendors may be available as downloadable support packages.

Elapsed time is 93.893302 seconds.

And, of course...

>> s = daq.createSession('nidaq')
The vendor 'nidaq' is not known. Use 'daq.getVendors()' for a list of vendors.
 
>> s = daq.createSession('ni')
The vendor 'ni' is not known. Use 'daq.getVendors()' for a list of vendors.

Success! I

• uninstalled all the VISA drivers for the NI cards with 17.5,
• logged in as admin,
• ran MATLAB as admin and registered the nidaq card

From that point forward, things worked. Not sure that was the smartest solution, but it worked... Still takes 90 seconds to issue the first daq command, but at least I can blink lights again! I did not end up needing to update the drivers past 17.5 nor did I end up needing to download the support package. It was ALL about the VISA drivers.
