Error message when you try to open a file that is associated with a file name extension that has uppercase letters:"The RDP file has settings that cannot be overridden by command line. The remote connection cannot be started"

Symptoms

Consider the following scenario on a Windows Server 2008-based computer:

You create a remote application and then publish the remote application by using an MSI package.
You use an associate file name extension. And, you sign off by importing a signing certificate to a test client.
On the test client, you create a file that has uppercase letters in the file name extension, and then you open the file.

In this scenario, the file cannot be opened. Additionally, you receive the following error message:

The RDP file has settings that cannot be overridden by command line. The remote connection cannot be started.

To work around this issue, rename the file so that it has lowercase letters in the file name extension.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section of this article.
