title: Register type library x64 regtlib
body: <p>I'm running Windows 7 x64, and need to register a type library file (.tlb).  I've done this previously (on a Vista x64 machine) but neglected to take notes as to how I achieved it...</p>
  
  <p>There is no regtlib.exe / regtlibv12.exe on the system.  I have copied across the regtlibv12.exe from a Windows XP system, however this will "not run".</p>
  
  <p>I have also attempted to register the TLB via "regsvr32" (tried using both the 32 and 64 bit versions) however always get the "Windows system mismatch" error.</p>
  
  <p>I have been performing these operations using an elevated privilege command prompt.</p>
  
  <p>Can anyone help?</p>
