Can't install mods with vortex, "system.configuration" missing

[Guest deleted52352441]

I recently reinstalled windows on an SSD and tried to move all Skyrim mods for Vortex over from my old drive to my new. It didn't work so I decided to do a fresh installation. I've reinstalled both SkyrimSE and Vortex completely on my new drive, complete fresh installation, and I can't install any mods. I get the error that my system is missing "System.configuration". I don't know what to do, please help.

Make sure you've done all required Windows Updates. It sounds like you may have an outdated .NET framework or something.

System.Configuration is part of the .Net framework. You need to install the .net framework in a sufficiently current version.

(Windows 10 includes a sufficient version by default btw.)
