EmailButton PrintButton

Below is a link to the current Quadra/D4 USB Driver Installer package. This is a zip file, after downloading extract it into a temporary folder. The contents of the temporary folder can be burned onto a CD-ROM disc or copied to a flash drive.

This is the same Driver Installer found on the Quadra/D4 Installation Disk normally used to install software. It is made available here as a download in case the full Installation disk isn't available and USB drivers must be installed or re-installed.

Two versions of the installer are included, one for 32-bit Windows PCs and another for 64-bit Windows PCs:

  • "dpinst-x86.exe" for 32-bit Windows
  • "dpinst-amd64.exe" for 64-bit Windows

To start the installer:

  • In Windows File Explorer, navigate to the location holding the unzipped files and double-click on the appropriate .exe file.
  • Click the Start button, click Run... and browse to the location holding the unzipped files. Select the appropriate .exe file and click OK.

The installer will open and walk you through the driver installation process.

If you burn the package onto a CD-ROM or flash drive, it will also be suitable for use with the Windows "New Hardware Found" wizard in Windows XP and Vista, or for updating drivers in the Windows Device Manager. See the USB driver installation instructions to learn more.
