Access Violation 0xC0000005 Crash When Starting LabVIEW

Issue Details

• When trying to start LabVIEW, it crashes and throws:

Error 0xC0000005 (Access Violation).

Solution

• If you have a volume license or are getting access to LabVIEW via a server on your company's network, verify your computer's communication with your network
  • Make sure your network cabling is functional
  • Make sure the NIC (Network Interface Controller) for your computer is connected
  • Make sure there are no network ports blocked by a switch/router
• Run LabVIEW as an administrator. To do this, right-click on the program in Windows Explorer and select Run as Administrator.
• Make sure you've installed the latest patch for your LabVIEW version. Patches will often address the most common causes of LabVIEW crashes.
• If you identified the VI that is causing the crash, try to recreate the VI from scratch and replace it in the project.
• If the crash occurs when opening a specific project, try creating a new project and move all the VIs and required files to it. Then, save the project and use it instead of the project with problems.
• Force reinstall LabVIEW.
  • After the force re-installation is complete, rerun the program as an administrator
• Uninstall LabVIEW, re-download the installation media, then reinstall LabVIEW from the new installation media files. 
• Uninstall all NI software from the NI Package Manager, then uninstall the NI Package Manager, manually delete the following folders, and Install LabVIEW:
  • C:\Users\<Username>\Documents\LabVIEW Data
  • C:\Program Files\National Instruments
  • C:\Program Files (x86)\National Instruments
  • C:\Users\<Username>\AppData\Local\National Instruments
• If you upgraded your operating system, confirm all NI software installed is still compatible: 
  • NI Product Compatibility with Windows 11
  • ​NI Product Compatibility with Windows 10
  • NI Product Compatibility with Windows 8
  • NI Product Compatibility with Windows 7
• If any software is not compatible, disconnect any NI hardware connected to the computer and uninstall  the version of the incompatible software. Then, install the compatible version and restart the computer.
• An access violation error may be, but is not always, caused by a lack of permissions. This may happen when trying to start a program you don't have access to or when a file tries to access a folder it doesn't have access to. The problem may be due to a lack of administrator privileges, which may be caused by anti-virus software.
