NI-VISA Passports are Missing in NI MAX

Software

  • LabVIEW
  • Measurement & Automation Explorer (MAX)

Driver

  • NI-VISA

Issue Details

  • I'm attempting to activate/deactivate a VISA Passport in NI MAX, but it doesn't show up anymore
  • The NIVisaTulip.dll passport is missing in my List of Passports in NI MAX 

Solution

If either of the passports is missing, it's very likely it was removed or installed incorrectly at some point. The solution to this could be force reinstalling NI VISA driver following the article Force Reinstall Non-Working or Corrupt NI Software. This will install any missing passports as well as it will correct for any potential corruption that the driver package might have. 

Additional Information

If a VISA passport was installed correctly, its associated DLL will show up both under NI MAX >> Tools >> NI VISA >> VISA Options >> Passports and under the folder X:\Program Files (x86)\IVI Foundation\VISA\WinNT\Bin.
