I just wanted to let you know that the instructions on installing drivers for VEXcode IQ with MSI installers need updating: https://kb.vex.com/hc/en-us/articles/360037761471-Installing-VEXcode-IQ-with-MSI-Installers
Your Generation 2 brain drivers are actually signed with a different certificate that is not listed for download on the support page. Therefore, when you use a powershell script to install the drivers, the pnputil.exe utility will kick back with the error “The publisher of an Authenticode ™ signed catalog has not yet been established as trusted”. What I had to do was extract the certificate from the IQ2 cat packages and add that to trusted publishers, only then would the drivers install.
Hope this helps someone in the same position. Developers, please consider updating the Code Signing certificates on the IQ2 packages.
