<p>I had issues with Citrix XenApp 6 and Windows Server 2008 R2 server.</p>
<p>When I tried to run published application (.exe) file on Citrix, I received the following message.</p>
<p>Open File &#8211; Security Warning &#8221; The publisher could not be verified. Are you sure you want to run this software?&#8221;</p>

<p>You can also get this warning if you try to run .exe file from a network location.</p>
<p>Solution:</p>
<p>There are two possible solutions, but the first solution didn&#8217;t help me, so I had to use the second solution.</p>
<p>1. Open Internet Explorer | Tools | Internet Options | Security<br />
Now select Local Intranet | Sites<br />
Check all of the three selection boxes.<br />
Now add the server as: <a href="file://\\Servername\">\\Servername\</a></p>
<p>2.Open Start | Run and type gpedit.msc. Click OK<br />
User Configuration | Administrative Templates | Windows Components | Attachment Manager<br />
Add *.exe to the Inclusion list for moderate risk file types setting. You can also add other extensions if needed.</p>
<p>This will disable the &#8220;Publisher Could Not Be Verified,,&#8221; messages from appearing for the specified file type.</p>
