title: Why does windows side by side (winSxS) install policy for auto upgrade when there are known issues between versions?
body: <p>We have an app compiled using MSVC 2K5, SP1 (version 762 msvcrt80)</p>
  
  <p>All is well, right up until somebody installs on the same machine .Net3.0SP1, and along with it msvcrt80 version 1433 is installed and a policy to automatically upgrade.</p>
  
  <p>Now we have random crashes all over the place and unhappy customers.</p>
  
  <p>I understand we can adjust our manifest files to force the usage of a specific version, but I've only found the really ugly way of copying detail that is auto generated and modifying it by hand.  This is especially unpleasant with a large number of apps to fix</p>
  
  <p>Can we instead get rid of the stupid 'upgrade' policy in the winSxS directory?
  Is there an option/flag to compile for a specific version only and still automatically generate the manifests?</p>
