After launching the Internet Explorer application, users receive the following error message inside a dialog box:

“Windows cannot find ‘(null)’. Make sure you typed the name correctly, and then try again. To search for a file, click the start button, and then click Search.”


This error occurs if you publish Internet Explorer in Explorer mode with the –e switch in the path.

For example:
C:\Program Files\Internet Explorer\iexplore.exe –e \\computername\foldershare

This issue occurs because of a design change in Internet Explorer 7 and later. Refer to for more information.


Publish the share as content in the Citrix console using the Universal Naming Convention (UNC) address \\computername\foldershare with permission to view or execute is required.


Publish Firefox.exe with a share path. For example:
C:\Program Files\Mozilla Firefox\Firefox.exe \\comptername\foldershare


This issue is currently reproducible with Microsoft Remote Desktop Connection using the Start the following on connection setting under the Programs tab.

The application can continue working after clicking OK on the dialog box. The message does not render the program unusable.

This error message does not occur with Internet Explorer 6 because of the integration between the Explorer.exe shell and Internet Explorer.

Microsoft does not recommend running Explorer.exe as a published application because the published Explorer.exe application runs as a separate process that has restricted access to the desktop.
