Pictoric,

We haven't tried running DNI in medium trust, and my understanding of the 3rd party Authorize.NET component used is that it won't run in medium trust. I've emailed Olvio about this in the past but they did not resolve the issue.

I apologize for the trouble. If this means you cannot run our software please contact us at support@dotnetinvoice.com and I can provide you with a refund. 

I moved my installation onto a different server that isn't shared, so I'm OK...  It would be nice to be able to run this application in Medium Trust..   Also, just an FYI, the following code from da.vb can not be run in medium trust:

 oConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~/")

 You have to use the configurationmanager.connectionstring  in medium trust.

Thanks for the info. I've added this to our issue tracker and we'll get this patched for the next release.

Our reliance on the Olvio Authorize.NET dll means we still won't be able to run in medium trust environment, but at some point if we decide to re-write their code we'll be in a better place to make it work.

Thanks again,
