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.
