how to check the a particular application is install or not in a machine using c#
<p>the requirement is "I want to a program in c# which only check that a specified program is installed or not in a machine" and show a message that the program is installed or not.</p>

<p>Actually, I have a project program in c#, I want that after loading my project first form the application first check the VSS is installed on my machine because VSS is required for my project.</p>

<p>My Operating System is Windows 7.</p>

<p>Thanks
