While you try out Apryse SDK without a license key, it is running in demo mode. One side effect of this is that your application will need read/write access to the registry enabled. The licensed version does not have this requirement.

This is a problem in running the demo version in an environment with restricted permissions such as when developing a Windows service or a server application.

The demo version has been used on servers with tight security by modifying a config xml file that controls security settings or using a Code Access Security Policy tool. For more info please see:

When running in a server context, you may encounter the following error if registry access is not available to the application. Please contact support for more guidance.
