I had exactly the same error and fixed it by changing the site's application pool to run under the Network Service.

In IIS:

  • Select your site's application pool
  • Select Advanced Settings on the right-hand side
  • On the Advanced Settings pop-up window, scroll down to the Process Model group
  • Change the first option called Identity to NetworkService (mine was set to the default ApplicationPoolIdentity).

I hope this helps.

I know this topic is old but just for future people who will be looking for this issue Just use this method to execute the code with Elevate privileges

using (HostingEnvironment.Impersonate()) {     // This code runs as the application pool user     }
