using tlbimp and Security issue

[AgentM]

I am using a unmanaged dll in my project. I converted the dll to a Managed dll using tlbimp

<code>
filename.dll /out:NetFileName.dll /transform:dispret
<\code>

The project compiles fine on my machine.
But when I move the exe to the server, it crashes giving the System.Security.SecurityException error.

Any ideas to get rid of this error.

Thank you
