NI Vision Acquisition Express VI is Not Displaying Any Image

Updated Dec 7, 2023

Issue Details

I am using LabVIEW and Vision Acquisition module to capture an image from my camera. I configure my camera and grab the image by using the Vision Acquisition Express VI. When I open the Vision Acquisition Express VI, the pane window (which is supposed to display the image) it is permanently grey and frozen, even though the frames per second are displayed:

When I run the top level VI which includes the VAE VI, I am able to observe the image indicators coming out of the function. 

Why do I see this behavior on the Vision Acquisition Express VI interface, and how can I solve the issue. 
 

Solution

The above symptoms are a sign of a software corruption, as the interface is behaving unexpectedly, while the VI is able to acquire and configure images. 

It is recommended to do the following steps to solve the issue: 
  1. Uninstall LabVIEW and Vision Acquisition SW
  2. Install LabVIEW
  3. Install Vision Acquisition SW
