  <p>When i use the same Dll's in Windows Forms it works fine. but when i place in IIS I'm getting the above error.</p>
  
  <p>I tried all possibilites like "Enable 32 bit applications", "Change Platform to X86","register the dll's in SysWOW64 using regsvr32","provide everyone permissions to that Dll's".....</p>
  
  <p>Can any one suggest , it helps a lot to me.
  Thanks.</p>
