title: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))
body: <p>I have a project which runs in visual studio 2008. When I try to convert the project within visual studio 2012 (on a different computer) I get the following error:</p>
  
  <p>Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))</p>
  
  <p>I have included all references and do not know where I am going wrong. I have one reference which is a third party .dll - it has a prefix ax. I also have references to AxInterop.MSCommLib.dll and Interop.MSCommLib.dll. I have tried setting the target platform to x86 and this does not solve this issue. I have also tried registering the .dll files but get the following:</p>
  
  <p>The module "interop.mscommlib.dll" was loaded but the entry-point DllRegisterServer was not found</p>
  
  <p>Any help would be much appreciated.</p>
