I was converting a company's VPNs to SSL, all worked ok except on a MS Surface Pro is an ARM64 based PC

The tablet has Win 11 Pro - 10.0.22631 Build 22631

When I try add an SSL VPN is says "Can't find VPPP adapter !!! - Not support VPN dialling type on current OS !!!"

The DrayTek Virtual PPP Adapter is missing from the Device Manager list and when I try to add it manually it doesn't accept the inf file.  Just doesn't add it.

Anyone had similar?
