Issue Details

I am building my LabVIEW code into a standalone application with the LabVIEW Datalogging and Supervisory Control Module (DSC). In the build specifications, I have chosen the option to Enable Enhanced DSC Run-Time Support and when I build the application, I get the following error:

Code:7
Error copying files.
Source: C:\Program Files (x86)\National Instruments\LabVIEW 2020\AppLibs\fflvapp.lib
Destination: C:\Users\cmill\AppData\Local\Temp\lvapp.lib.tmp

Possible reason(s):

LabVIEW: (Hex 0x7) File not found. The file might be in a different location or deleted. Use the command prompt or the file explorer to verify that the path is correct.

If I build the application without Enhanced DSC Run-Time enabled, the application builds without error.

Solution

If you see this error, it is likely that a component of the DSC Module, fflvapp.lib, has not been installed correctly.
To fix this, uninstall the LabVIEW DSC Module and then install it again, which should install this file.
