You must download and install the Vishay driver then locate the VI mentioned in the dialog.

Easy way is to use the Instrument Driver Finder.  Look here to learn hos to install instrument drivers - https://www.youtube.com/watch?v=Xx5NqiLj1wY

If your driver isn't installed  through the driver wizard, but downloaded from the vendor and installed somwhere else on your HD then you can either..

1) copy the directory to one in your picture then select the right VI.

2) use the Browse feature in that dialog to locate the right VI.

It's "Vishay driver "already installed

Hi Jana,

while loading a VI LabVIEW is searching for subVIs and typedefs.

Apparently there is a typedef missing in the place where LabVIEW expects it to find.

You need to find the missing VI or typedef on your own using the browse button…

Atleast your image is showing that behaviour: it currently is searching in the typedef subfolder of the Vishay device driver. But it also tries to load that "Pendubot Nonlinear Model - Final" VI from your user folder: have you deleted or renamed that VI?

Hi jana,

the file opened but it didn't run it has an error list 

Then you need to solve those errors!

(You might get help once you show that error list…)
