title: How to Deploy multiple versions from one Project
body: <p>I have an .Net 4.0 solution, and i use Visual Studio 2010.</p>
  
  <p>in that soulution there is an startup project. I deploy the Project with the Webdeployment method, onto the IIS, the client can then go to the publish.html of the corresponding website, and install the application.</p>
  
  <p>My problem starts when i try to release two different versions of that prooduct and try to install both on the same machine, then the installer thinks that the application is already installed. (after i install the first version of the product, the installer then complains that there already is an app with this name but i changed the product name)</p>
  
  <p>How can i publish two different versions of my project, on two seperate websites? and have them install on the same machine at the same time?</p>
