title: Register DLL in GAC without Assembly Manifest
body: <p>I have a DLL I wish to register with my GAC.  I enter the command:</p>
  
  <pre><code>gacutil /i c:\temp\msvcr100.dll
  </code></pre>
  
  <p>and I get the error:
  <PRE>Failure adding assembly to the cache:   The module was expected to contain an as
  sembly manifest.</PRE></p>
  
  <p>All I have is the DLL.  Is there a way to create / fake / bypass it?</p>
  
  <p>For those interested, I am attempting to extract the Visual Studio 2010 &amp; .NET 4.0 CTP from the VHD and run it on my physical box.  As a side note, has this been attempted?</p>
