Uploader Notes

When extracted, this file contains the executable main installation file EMPW1_7.MSI and two USB driver files.

This is V1.7 of the Needhams Electronics EMP series device programming software for Windows- the final release before Needhams Electronics went out of business.

This file was obtained from a third party who uses this software for their own applications.

It will also reportedly run with the 32 bit versions of Windows XP, Vista, and Windows 7. It will not run in the 64 bit versions because the USB drivers were written for 32 bit, and will not work in the 64 bit versions.

Since Needhams Electronics has gone out of business, there is no longer any factory tech support.

Please refer to the Windows programming manual for directions.

How to Open Device Manager

  • In Windows 10 & Windows 8.1, right-click the Start menu and select Device Manager

  • In Windows 8, swipe up from the bottom, or right-click anywhere on the desktop and choose "All Apps" -> swipe or scroll right and choose "Control Panel" (under Windows System section) -> Hardware and Sound -> Device Manager

  • In Windows 7, click Start -> Control Panel -> Hardware and Sound -> Device Manager

  • In Windows Vista, click Start -> Control Panel -> System and Maintenance -> Device Manager

  • In Windows XP, click Start -> Control Panel -> Performance and Maintenance -> System -> Hardware tab -> Device Manager button

How to Install a driver from Device Manager

  1. Locate the device and model that is having the issue and double-click on it to open the Properties dialog box.

  2. Select the Driver tab.

  3. Click the Update Driver button and follow the instructions.

In most cases, you will need to reboot your computer in order for the driver update to take effect.

Tech Tip: Driver downloads and updates come in a variety of file formats with different file extensions. For example, you may have downloaded an EXE, INF, ZIP, or SYS file. Each file type has a slighty different installation procedure to follow.
