The LINX version 3.0.1.192 was released in 2016 to go with the then newly released LabVIEW Home Bundle, which was based on LabVIEW 2014 SP1. The references in your image to a release 3.0.0.186 is pretty odd.
Problem Installing LINX on LabVIEW 2024 (Error Code 1003 - NI Community
I had same issue that you had (Labview 2016, MakerHub LINX 2.0.0.35, Arduino ADK) and your solution solved this issue. I had an other configuration (Labview 2016, MakerHub LINX 2.0.0.35Linx, Arduino UNO) where the original LINX software worked well.

The Digilent Linx version 3.x.x is NOT compatible with LabVIEW 2020. And it is not needed when you install the Community Edition as that installer comes with the NI Linx Toolkit version 1.0.0 already in it.
Sam and supposedly others were continuing on Linx while at Digilent but somewhere around 2016 this pretty much stopped until it was revived for inclusion into the LabVIEW Community Edition in 2019. At least since that time it was fully open source on github but most likely it was before, I just didn't happen to hear about it.
Being totally new to LabView and the Arduno Uno, so far, after uploading the LINX firmware to the Uno, I've been able to successfully combine the LINX example code for Digital Read, Digital Write and Analog Read into the following BD: While not a major feat, it runs without errors - at about 50hz...
The MakerHub LINX package is installed via the JKI VI Package Manager, which has become the defacto standard for installing LabVIEW addons. The host PC in the guide is running Win 7 64-bit. The install steps may be different for other operating systems. As I understand it, Mac or Linux systems are not currently supported with LabVIEW-LINX.
