The ActiveX palette item is not properly linked to the ActiveX control, so LabVIEW is unable to find the correct path to the ActiveX control on disk.
To fix this issue it may be necessary to repair the LabVIEW run-time engine.
- Navigate to Control Panel >> Add/Remove Programs >> National Instruments Software
- Select the appropriate NI LabVIEW Run-Time Engine and click Repair
- Restart your computer.
