I am working with SharePoint 2010. I need to activate SharePoint Publishing Infrastructure Feature under Site Administration>Site Collection features. But when I try to activate this feature I get the following error.
The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file. Exception Details: System.Security.SecurityException: Requested registry access is not allowed.
Could you please help me on this.
Kind Regards Vivek B
