Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.

Have you tried using the second method (through web request) or do you not even get to the license page? What trust level are you running under by the way?

Hi Peter,
I am having a similar issue. I have DNN 4.9.0, basically a clean installation and when I click on the license button I get the error. I never see the Licensing dialog at all. Here is more details about the error, can you help me with this?

Thanks,
Thomas

I guess you're in partial trust mode. Although DMX has been known to work in medium trust, the excat trust level is set by the admin on the machine. And you can lock it down to a level that some things start to fail. As an example: if the module is no longer allowed to perform disk IO it becomes pretty useless. Here it seems to scream that it is not allowed to serialize. The error is new to me.
Note that under partial trust the upload component won't function and you'll have to work with the regular asp.net file upload component.

Peter
