Problem using chart fx through other server, keyset does not exist


Recommended Posts

Hi, I made a c# web app that works fine on my development machine, however, when i publish out to another machine, and open the app through a browser,

when it first tries to create a chart using chart fx lite through a user control, i get this error:


Keyset does not exist

chart fx lite was installed on the server and the app published successfully to the virtual directory there. Any suggestions?

Hmmm well, i found a temporary solution.

 I changed the application pool property identity that it was running under from Network Services to Local System, and disabled anoymous access to the directory.

I would keep it as Network Services but I don't know where to give it read permissions...

Any suggestions?

The exception you are getting is due to a lack of permission to the registry required by .NET Cryptography provider. I do not know exactly what part of the registry they access and I couldn't find anywhere where they say it. So I can not tell you exactly what portion of the registry you need access to.
