DPP Installation Instructions

Amptek recommends the Professional version of Microsoft operating systems (Windows 7/8/10 Pro)

All Amptek current products (FW6) can be installed with the following instructions. For older hardware or firmware (FW4 or FW5) please see the Reference Information section below.


There are two steps to installing the software for an Amptek DPP device.

  1. Install the WINUSB driver
  2. Install the DPPMCA Display and Acquisition software

STEP 1: Install the WINUSB driver


If the computer does not have access to the internet, or if you are using an unsupported operating system, install the driver manually using the Manual WINUSB Driver Installation Instructions. You will have to download the WINUSB driver package (9 MB zip file) for manual installation. Only download the WINUSB driver package for a manual installation, it is NOT needed for Windows Update automatic installation. When performing a manual installation, follow the instructions in the document precisely and carefully. Making an incorrect selection will install the wrong driver and make it very difficult, error-prone, and time consuming to remove the incorrect driver from the operating system.

  • Installation Frequently Asked Questions (FAQ) +

    If I try the automatic install method for the USB driver but my device and operating system are not supported, what happens?

    The installer will go to the Windows Update site but will not find the correct package. It will eventually give you an error message that the “Installation Failed”. At this point, you must follow the manual installation instructions.

    Where can I get the latest drivers and software?

    Go to the DP5 Downloads page.

    My computer is asking to install the USB drivers again, even though I installed them previously. Why?

    Under the USB protocol, the drivers are installed for every USB port. Each time you plug a unit into a different port on the computer, the drivers must be installed.
