Control Could Not Be Loaded Error When Placing ActiveX Control on Front Panel

Updated Sep 18, 2024

Issue Details

  • When I try to place an ActiveX object from the ActiveX palette on the front panel I get the message "Control could not be loaded". How can I fix this?
  • I upgraded the versison of .NET Framework by updating National Instrument's software. Now the controls on my executables say "Control could not be loaded." How can I fix this?

Solution

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 you can try one of the following steps:

Additional Information


Note: This message can also occur if the ActiveX control uses the .NET Framework and this framework is not installed on the PC. In addition, it may happen if incompatible versions of the framework are being used when going from a development to target machine. For .NET versions 2.0 and higher are backwards compatible. For example, if the .NET Framework 3.5 is installed, aspects of the .NET Framework 2.0 can be used.
