If the initial launch of the Keyboard Wedge fails with the following error: "The feature you are trying to use is on a network resource that is unavailable", the installer files to perform the initial setup couldn't be found by the system.
If this is the case, we recommend copying the files to a local directory prior to installation to avoid this error. E.g. with deployment script as shown below: (see also How to build a Keyboard Wedge package for an automated deployment on Windows 10
copy %root%\*.* c:\temp\scandit
msiexec /i "c:\temp\scandit\KeyboardWedge.msi" /qn /norestart
