title: Visual Studio Packaging: Another version of this product is already installed
body: <p>I have a msi created for a project which uses C# &amp; Jscript. version-1.0 is currently public.  I want to release a bug-fixed version v-1.0.1 of this package but while testing it, I am getting "Another version of this product is already installed Installation of this version cannot continue.To configure or remove the existing version of this product, use Add/Remove program on the Control Panel".</p>
  
  <p>I want this bug-fixed version to install silently without asking user to uninstall and install new one.
  Please help me how can I achieve this, I am using visual studio 2008.</p>
  
  <p>Thanks in Advance!</p>
  
  <p>Sam</p>
  
  <p>Update: I have tried changing the package code but that creates two instances of the package using same working directory. Visual Studio geeks please help.</p>
