One of our customers purchased a license for EO.Pdf and we're trying to get to function in a partial trust environment. From what I've found on this forum this is not possible. But maybe it is :) Here's what we've tried, maybe we're missing something to get it to run properly:

* installed the assembly in the GAC
* added it as a fullTrustAssembly in the system web.config
* using Sysinternals Process Monitor, fixed all "access denied" errors on file system directories and registry keys

Now the question is: What "IPermission" class does it require (e.g which IPermission class needs elevated permissions, such as "ReflectionPermission", or does it have its own (like MySQL Connector/NET now has the MySqlClientPermission class)?

The Exception it throws is:

---

Any help is much appreciated.

Thank you for your reply. Not being able to run it in partial trust was my fear.

Are there any thoughts on making EO.Pdf run in partial trust? (this would also greatly benefit EO, as more hosting providers can support the assembly).
