# License ActiveReports

This topic provides links to subtopics that give an overview of all aspects of the licensing procedure in ActiveReports .NET.

## Content

Users can access the MESCIUS License Manager utility to license ActiveReports at the time of installation or if there is already a trial version installed.
To use ActiveReports development environments, you should buy a corresponding license. A common run-time license is embedded into the application with a general .NET mechanism - the **licenses.licx** file. You should update references in the file to use new ActiveReports versions.
