title: How to Solve 0x80040154 (class not registered) error?
body: <p>I work with windows form application, which need some .dll file.</p>
  
  <p>First time i finish it, build and run, it worked &amp; is fine. 
  (64 bit processor,64 bit Windows 7, Visual Studio 2012)</p>
  
  <p>And then, i copy and paste entire project to other PC (64 bit processor, 32 bit Windows 8, Visual Studio 2012).
  I couldn't run it, there is error message 
  "Class not registered, exception form HResult 0x080040154 (REGDB_E_CLASSNOTREG)"</p>
  
  <p>I have tried solutions :</p>
  
  <ol>
  <li>change platform from anyCPU to x86, didn't work</li>
  <li>Put all .dll file to system32 folder, didn't work</li>
  <li>Tried to register class using regsvr32, but i got error message said that my .dll file :
  "was loaded but the entry point was not found"</li>
  </ol>
  
  <p>And I can't even open my Form.cs[design] in Visual Studio,</p>
