All features of ActiveReports are available without restrictions in a Full trust environment. You can also use ActiveReports under Medium trust, but with limitations on some of the features.

Caution: Assemblies placed in the Global Assembly Cache, or GAC (C:\WINDOWS\ASSEMBLY), have Full trust permissions, so the results on your deployment machine may differ from those on your development machine.

Note: If you see an evaluation banner when deploying your ActiveReports project, you should use the Web Key Generator utility to create the Web Key and integrate the license information into your project.

Feature Limitations

1. Exporting
   • RTF, Text, TIFF and Excel filters are not supported in Medium trust.
   • Digital signatures cannot be used in case of PDF rendering extension and PDF export.
   • Chart and Matix control of Page Reports are not displayed properly in case of PDF rendering extension and PDF export.

2. The End User Designer and Windows Form Viewer controls require Full trust.
3. The Picture control does not support metafiles, which require Full trust.
4. The ImageType property of the Chart control must be set to PNG.
5. OleObject, FormattedText and Custom controls require Full trust.
6. Scripting requires Full trust, so if you need to use code in reports under Medium trust, use code-based reports rather than RPX format.  
7. WebViewer
   • Bullet, Sparkline and Calendar control of PageReports are not displayed in all the Viewer types.
   • Report containing the Image control of PageReports is not displayed properly in case of HTML type.

1. Open the web_mediumtrust. config file (located in the \Windows\Microsoft.NET\Framework\v4.0.30319\Config folder).
2. Set the PrintingPermission level to NoPrinting.

XML code. Paste BETWEEN the system.web tags.	Copy Code
<IPermission class="PrintingPermission"version="1"Level="NoPrinting"/>

Note: The default set of medium trust permissions is available in the web_mediumtrust.config.default file.
