title: Can I remove a digital signature from a DLL?
body: <p>My installer build "signs" a DLL using a Code Signing certificate during the build process. </p>
  
  <p>I've noticed that if I try to build twice in succession, the second build fails because the DLL is already signed so signcode chokes. Obviously I can fix this by signing a copy of the DLL in the build, but the problem intrigued me: </p>
  
  <p>Is it possible to "unsign" a DLL, and if not, why not...?</p>
