Windows version is 1909. I've tried with IPVanish, and with Logmein Hamachi.

IPVanish installs without incident, but if I try to tell it to install the OpenVPN driver, it fails every time, preventing me from using the OpenVPN protocol.

Hamachi installs everything, except it's "Logmein Hamachi Virtual Ethernet Adapter" which prevents me from using Hamachi at all.

both of these adapters are TAP Network Adapters, which tells me that Windows is refusing to allow me to install such adapters.

What I've tried: (Not listed in any order)
uninstall/reinstall both apps
Manual install of both adapters (Not at the same time!)
Disable Firewall
Disable Antivirus
Restart PC
Ran "chkdsk /f" on drive C
Ran "sfc /scannow"
Ran "dism /Online /Cleanup-Image /RestoreHealth"
Ran antivirus, and malware scans.

at this point, I'm kinda out of ideas, so any help would be greatly appreciated. If you need more info, don't hesitate to let me know.
