After downloading the PVS-Studio distribution and requesting a key to experience the tool, you'll get a fully functioning version, which will work for one week. In this version, there are absolutely no limits - it is a full license of the Team License category.
Differences between Enterprise and Team Licenses are given on this page. To research the capabilities of Enterprise License, just write to us and we'll provide you with such a license.
If a week was not enough to try out the tool, just request another key via the same feedback form and we'll send it to you. We ask to send a second request in order to ensure that you've tried working with the tool.
