Issue Details

I created a LabVIEW executable and when deploying to a system with a different OS it shows the following error message:
<Application name>.exe is not a valid Win 32 application

The error message looks like the one in the image below:

Solution

This issue normally happens if the LabVIEW Run-Time Engine is not installed on the deployment PC. The error message does not provide additional information about the LabVIEW Run-Time Engine since it was created a version of LabVIEW which is not compatible with the OS. To resolve this issue you have to install a compatible version of the LabVIEW Run-Time Engine with the deployment PC OS and rebuild the executable with this LabVIEW version. In the following link, you can check a complete list of LabVIEW versions and Windows OS compatibility: LabVIEW and Microsoft Windows Compatibility. After this, ake sure you install the LabVIEW runtime engine in the deployment PC by either creating an installer with the LabVIEW Application Builder or by installing it separately.
