title: Where is msvcp90d.dll supposed to come from?
body: <p>What is the story with the VC debug CRT?  where is it supposed to come from?</p>
  
  <p>in particular, on my machine, running both VS2008 and VS2010 I dont have the amd64 version installed in c:\windows\winsxs?  </p>
  
  <p>reading about this on the internet has been very confusing,  I feel that everyone is hacking around, copying bits to C:\windows\system32, etc.</p>
  
  <p>Where am I suppose to be getting the debug CRT and how do I correctly install it?  I see the binaries were copied to C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\redist during the VS install. </p>
  
  <p>now what?</p>
