Solution
The following are some common errors that can arise if NI Vision products are not activated correctly:
Missing DLL Error
One error that could arise is that your executable, when run, will complain about a missing DLL file. This error is usually the result of not having the NI Vision Runtime Engine installed.
To check whether the run-time engine is installed:
- Go into Control Panel»Add/Remove Programs»National Instruments Software.
- Look through the installed programs and verify the presence of an entry like NI Vision Runtime XX.
Note: Missing DLL errors can also indicate that the Vision Acquisition Software (VAS) drivers are not installed.
Invalid License Error
This error can occur if you have both the Vision Development Module (VDM) and the VDM Run-Time Engine (RTE) installed, but VDM is not activated. To resolve this error
activate or
uninstall VDM.
Note: The VDM RTE does not require activation on computers with VDM activated. However, if VDM is installed but not activated, executables using VDM VIs or functions will not execute and will give an invalid license error even if VDM RTE is activated. If VDM is installed, the NI Vision software only confirms that VDM is activated and does not check the status of VDM RTE.
Unlicensed Copy Error
The following error message only may arise when you have not properly installed the Vision Development Module Run-Time Engine on the target machine.
This unlicensed copy of Vision may be used for demonstration purposes.To solve this problem, try the following:
- Manually run the Vision Run-Time Engine installer on the target machine (for example visionXXrte.exe for Vision Development Module X.X, where XX is the version of the Vision Development Module) and the error message should go away.
- For Vision 8.0 and later, you can include the Vision Development Module Run-Time Engine in your LabVIEW installer. Additionally, ensure that if you are using VIs from the Vision Development Module that you have the Vision Development Module Run-Time Engine, not just Vision Acquisition Software.
Technical Problem During Activation
If you see an error message similar to the following when activating using your serial number, try going to
