Solution
Troubleshooting
Start by checking the most recent system update that occurred before the issue began. For NI software that relies on shared components or registry configurations, improper uninstallation of applications or packages—or leaving dependencies unresolved—can lead to potential issues.
If corruption is suspected, upgrading the software is generally recommended. However, because error 0xC7FBEC5C:「OMClass.cpp」line 12xx is typically caused by corrupted files in the Windows registry, the most effective solution is to perform a clean installation of the Windows operating system. This will reset all components and dependencies left behind by previous installations or improper uninstallations.
If a clean install is not possible, consider the following workarounds:
- Force-reinstall: If your software was installed using individual product installers or suite installers (without NI Package Manager), try the force-reinstall option.
- LabVIEW Directory Cleanup: The LabVIEW folder is not deleted during an uninstallation. When performing a reinstall, there is a possibility that unwanted or corrupted files and folders may be retained. This also applies to the "Repair" option. If LabVIEW was installed through NI Package Manager or if the force-reinstall option does not resolve the issue, rename your current LabVIEW directory and reinstall it to the default path:
- 64-bit systems: C:\Program Files\National Instruments
- 32-bit systems: C:\Program Files (x86)\National Instruments
