title: Sandboxing applications
body: <p>I have an application (Installed as a service) that has 5 different versions. For testing I need to have all 5 installed. Currently I have to uninstall the application and reinstall the required version.</p>
  
  <p>The application has a single exe (in Program Files\App) along some an xml file containing it's settings. This is installed via an MSI file. Each version has the same file\service name and checks for previous versions before installing.</p>
  
  <p>Any ideas on a way to run all five versions at the same time?</p>
