Windows 7 Certificate Handling

This installer addresses the "untrusted certificate" issue on Windows 7 systems that lack updated root certificates:

What It Does

1. Installs Certificate: Extracts the Xerox signing certificate from the driver catalog (.cat) file and adds it to:

   • TrustedPublisher store - Trusts the driver publisher
   • Root store - Validates certificate chain

2. Modifies Signing Policy: Sets driver signing policy to "Warn" (not "Block") via registry:

   • HKLM\SOFTWARE\Microsoft\Driver Signing
   • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\DriverSigning

3. Multiple Install Methods: Tries several approaches for compatibility:

   • pnputil /add-driver (Windows 10+ syntax)
   • pnputil -a (Windows 7 syntax)
   • rundll32 setupapi.dll,InstallHinfSection (fallback)
   • rundll32 printui.dll,PrintUIEntry (driver registration)
