This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.


This issue may occur if there is a Group Policy object (GPO) that restricts what programs you can run. Programs can be restricted if either of the following policies in the domain organizational unit group policy or a local computer group policy have been applied:
  • Do not run specified Windows applications.
  • Run only the allowed Windows applications.


If you need to run a restricted program, contact your system administrator to modify the GPO.

If you are an administrator, you can verify the policies that are enabled. To do this, click User Configuration, click Administrative Templates, and then click System.
