title: Multiple msvcr100.dll versions - where are the differences?
body: <p>When deploying my app, the 2010 redistributable package x86 is needed. Having customers install it by themselves online is cumbersome. I would like to deploy msvcr100.dll and msvcp100.dll myself, which would work fine... However, on my system I can find multiple of these dlls. There is a <code>redist</code> folder in the Visual Studio 2010 directory and I used dlls from there, but they do not seem to work globally, either.</p>
  
  <p>I know most of the threads, questions and articles to visual studio deployment on Stackoverflow and findable via Google. None gives a satisfying answer.</p>
  
  <p>But my question here is: Are there multiple versions of msvcr100.dll globally available? If yes, why and how do they differ?</p>
