title: Visual Studio 2010 Warning: Unspecified error (Exception from HRESULT: 0x80004005 (E_FAIL))
body: <p>I see quite a few posts on this error but none seem to relate to my situation.  I have a small solution containing 2 winforms apps and a data access DLL.  I am using VS2010 with SP1.</p>
  
  <p>When I open the solution on my Vista Business 32 bit SP1 laptop it all works no problems.  However when I open the exact same solution on my Vista Ultimate 64 bit SP1 desktop I get the above error as soon as I open the solution and each time I attempt to build the solution.</p>
  
  <p>There are no unusual tools, components, or libraries installed or used in the solution so it has me very confused.</p>
  
  <p>Any advice would be very much appreciated!</p>
  
  <p>Thanks and kind regards.</p>
