Unless you have LabVIEW 2014 installed, you install the wrong piece of software!
The Digilent Linx packet only works for LabVIEW 2014 (SP1) and nothing else.
You need to install the NI Linx Toolkit and that only works for LabVIEW 2020 and newer. And if you installed the LabVIEW Community edition, don't try to install ANY Linx Toolkit software, it is already included in the LabVIEW Community and trying to install any version of the Linx Toolkit only can make it inoperable but definitely won't fix whatever you think you need fixing.
