How can I change the RDS Application Icon which appear in VMware Horizon View Client ?

Hi,

I have to deploy the application pools to the user in VMware Horizon View environment using RDS feature on the Windows Server 2012. When I tried to publish the application I noticed that the icon is a little bit strange.

If I select the application from the lists, the application show up with right icons -- such as (remote desktop, notepad, wordpad, IE, paint)
But if I add the application manually, there are something wrong the application show up only "A" icon. If I add more applications, the icon are the same picture. -- see an attachment below.

Can I change the icon appear on the Horizon View Client ? How can I change it ?

Thanks in advance.
