Message - the publisher could not be verified

Modified on: 2017-09-22 13:52:14 -0400

When opening Design Manager a message appears that states 'The publisher could not be verified. Are you sure you want to run this software?'

This problem usually occurs when the program is loaded on a network drive and has three possible solutions:

  1. The client setup or setup is not installed properly.  MAKE SURE YOU HAVE A GOOD BACKUP BEFORE UNINSTALLING!  Uninstall DM or the client, reinstall and make sure that installation is pointed to the shared or network location so that the program can be registered properly.
  2. When on a peer to peer network, removable drive, or other shared resource and using Internet Explorer 7 or higher you must set the network resource as a safe zone:
    • Opened Internet Options Dialog Box from IE7
    • Select Security Tab
    • Select 'Local Intranet' icon from the zones shown
    • Clicked on 'Sites' command button, which opened a 'Local Intranet' Dialog Box
    • Clicked on 'Advanced' command button, which opened a dialog box where you are able to add and remove websites from your intranet.
    • Add '\servername\' to list of websites. Click 'Close, then 'OK' to return to main Internet Options Dialog Box. The default security level should be OK to allow to run the EXE stored on the network drive.
  3. If the network resource is a controlled by a domain controller, make sure that the workstation having the problem is a member of the domain and that the program was installed under a user that is a member of the domain.  Make sure that the network resource is a safe zone in the eyes of the domain.

Running XP Pro SP2 or higher, you try to run an executable located on another machine on your network. You are accosted with a prompt: 'The publisher could not be verified'. You are forced to confirm that you wish to run this program...every time you run it.


In the Start, Run command box type: gpedit.msc

Go to: User Configuration >> Administrative Templates >> Windows Components >> Attachment Manager

Add the '*.exe' name to the 'Inclusion list for moderate risk file types' setting.

This policy setting allows you to configure the list of moderate risk file types. If the attachment is in the list of moderate risk file types and is from the restricted or Intranet zone, Windows prompts the user before accessing the file.

In other words, this allows you to run an .exe from the Intranet zone without a prompt, but it will still warn before running one from the Internet.


This problem cannot be fixed for XP Home because XP Home does not support group policies and cannot be members of network domains.
