Yes, the application will work on Windows 7, however you should keep in mind that the product isn't actively supported anymore. I've tested it on Windows 10 and it displays the maps and I was able to select an area an even input a ZIP code. When I clicked the map to zoom it, a new browser window opened with the large map.
