Installing the Windows Credentials Provider to a Server 2003 or Windows XP machine displays a VBScript error and an error titled, "AuthAnvil Windows Credential Provider Setup Error":
This product requires at least User Account Control Elevation.
Setup cannot continue.
The Windows Credential Provider is only able to be installed on Windows Server 2008 / Windows Vista or later. User Account Control was introduced in these operating systems so any older operating system will fail to even run the installation correctly.
Download and install the Windows Logon Agent (Server 2003 / Windows XP) from http://www.scorpionsoft.com/downloads/2fa under the AuthAnvil 2FA Agents tab.
