1. The application doesn’t work in standard user.

When the shortcut is launched the icon appears in the taskbar and disappears suddenly.

When shortcut is launched the application creates a log file in Appdata\Cisco\Click to Call\Log

The log file states that HTTP could not register URL http://+:22222/REST/. Your process does not have access rights to this namespace (see http://go.microsoft.com/fwlink/?LinkId=70353 for details). ---> System.Net.HttpListenerException: Access is denied

To resolve the problem we need to register the URL mentioned in the log file.

Write a custom action to register the URL using netsh command

Netsh.exe http add urlacl url=http://+:22222/REST user=everyone

Note: Here the user can be any valid user/group in the environment.

Write a custom action to unregister the URL using netsh command

Netsh.exe http delete urlacl url=http://+:22222/REST

 2.  When the shortcut is launched first time, browser is opened which displays the help file of the application

Add the following registry to suppress the window.

HKCU\Software\cisco\clicktocall

DWORDVALUE: done

Value Data: 1

Note: The remediation is only applicable to Windows 7 as netsh.exe is not supported in Windows XP. HTTPCFG can be used instead but the tool needs to be downloaded for the command to be used.
