title: Missing DLL in Release but not in Debug
body: <p>I am porting an old MFC application from Visual Studio 2008 to Visual Studio 2019.</p>
  <p>In the process, an old DLL library has been incorporated into the source code to remove the library building step in development.</p>
  <p>Now, this program runs and functions perfectly when debugging in the default Debug configuration; however, in the Release configuration I get:</p>
  <blockquote>
  <p>The code execution cannot proceed because <code>MSVCR90.dll</code> was not found</p>
  </blockquote>
  <p>I imagine this means that <code>MSVCR90d.dll</code> is successfully found in Debug mode, but cannot find the release version of the DLL for some reason.</p>
  <p>I've tried all the general steps of downloading Visual C++ Runtime redistributables, changing to statically linked runtime libraries, and most other things found in the first results on Google.</p>
  <p>All intermediate versions of Visual Studio are installed locally on the development machine (2008, 2010, 2015, 2017, and 2019).</p>
  <p>Is there anything else I could try?</p>
