I did some checks myself in the MSI using Orca:
Will the property MODE_WU=TRUE be a solution. This seems to skip this custom action. But does it harm when i skip it ?
Which wireless adapter do you have installed? Intel® PROSet/Wireless 13.0 is several years old and will not recognize newer hardware. You should try using the recently released version 15.1.1. You have 2 options for the files: Consumer or IT Administrator. If you are trying to do silent or unattended install you'll need the IT Administrator version.
