title: "unable to find a version of the runtime to run this application .net framework initialization error" after install
body: <p>I have a .net project which is currently set to utilise 3.5 of the framework, but for some reason all installs of the app seem to be broken now. I believe its related to either SP1 or 4.0 being install via Windows update as we have not updated the software.</p>
  
  <p>On my PC here the app (with some tweaks) runs fine from Visual Studio 2008 but if I use the WIX Setup project to create an installer and install the software I even get the same error running the project from my PC.</p>
  
  <p>Any idea how I can debug the program and find out whats causing the error? (Ive inherited the solution so the WIX side of things is a bit lost on me, but it seems straight forward)</p>
