Application fails to load from network drive with PolicyException

[Maksim Chepel]

In my app I use some COM objects and as long as this app is on local C drive
it loads fine. As soon as I copy the app to a mapped network drive it fails
to load with "System.Security.Policy.PolicyException: Required permissions
cannot be acquired."
Why would that happen?

[Valery Pryamikov]

Because when you run it from the mapped drive, your code is assigned to
local intranet code group which is not allowed to call unmanaged code.

In my app I use some COM objects and as long as this app is on local C

fails
to load with "System.Security.Policy.PolicyException: Required permissions

Why would that happen?

So what to do?

You can either run your code from local computer zone or use Microsoft .Net
Framework Wizards or Configuration (from Administrative Tools) to raise
trust for your assembly.

instalation?

Yes it is possible if you have setup/msi install file.
You can find such sample msi setup on Chris Sells's web site

Thanks a lot! I'm guessing it's doable from the .NET studio, right?
