When building an installer using the LabVIEW Application Builder, I get Error Generating Preview. Why is this happening and how can I fix it?


  • If you are using LabVIEW 2013, refer to this KnowledgeBase article for details on the CAR and fix.
  • Otherwise, a common cause of this error is conflicting or missing dependencies. You can find conflicting items by viewing the full path of an item by right-clicking on the project root and selecting View >> Full Paths. You can also go to Project >> Resolve Conflicts to display the Resolve Conflicts Dialog Box. See Resolving Project Conflicts  for more details.
  • Make sure that all VIs listed in the Always Included section of your build specification are called in the executable(s) being installed. The 
    message can arise if a VI is always included but never called.Error Generating Preview 
  • Try deleting and recreating the Build Specification for your installer.
