PARLAY 2.0's license key can be installed on more than one computer, but for concurrent use of two or more people at the same time, you would need additional licenses. You can manage your subscriptions by logging in to reportallusa.com and then clicking on "Account". From here, just click on the PARLAY download link and this assigned KML file will allow you to access your subscription through both of your machines once you have downloaded and clicked on the file.
Organization-wide licensing, and multi-license discount options are available. Please contact firstname.lastname@example.org for more information.
