I came across a problem with the EvaluationMonitor class earlier today. I had developed a class library for deployment on a web server. All working fine - until I uploaded it to my ISP when it fell about. Reason being that the account didn't have permission to use the registry.

Which is fine, I understand why etc. It looks as though I am going to have to use encryption of data stored in a database to manage licensing constraints.

However I wondered whether there were any other "bits" of Infralution license management which I would need to be careful about in terms of using the registry?

The EvaluationMonitor is the only ILS class that uses the registry. Using the registry to store the encrypted evaluation data makes it that little bit more difficult for users to locate and tamper with it. It will use the HKEY_CLASSES_ROOT hive if there are sufficient permissions otherwise it will use HKEY_CURRENT_USER. If your application doesn't have permission to either of these then you won't be able to use the EvaluationMonitor.

This post gives me the opportunity to make a feature request: why not create a backup copy of the trial info in a file located in the isolated storage (either machine or user)? The name of the file can be an hash of the registry key for immediate and easy access by the licensing class. This can also improve security by having another checkpoint of not easy access for the user.

That is certainly something we will consider for a future release.

Version 4.6.0 now includes support for storing evaluation data either in registry (using RegistryEvaluationMonitor) or in Isolated Storage (using IsolatedStorageEvaluationMonitor).
