title: Error 1330. Visual studio 2008, cab11.cab has invalid digital signature
body: <p>When I am installing VS2008,via alchohol120 as it is ISO file, it gives me this error
  "Error 1330.A fiel that is required cannot be installed because the cabinet file g:\cab11.cab has an invalid signature. THis may indicate that the cabinet fiel is corrupt."</p>
  
  <p>I have tried few things like, choosing custom installation and unchecked option for SQL express and visual c++, but no help.</p>
  
  <p>Then I checked digital signature of cab11.cab, it has a red cross on it, tried to install certificate , but again no help.</p>
  
  <p>Even tried to copy the content of the folder to my HDD from virtual drive, but it says "File Integrity violated"</p>
  
  <p>So can any one tell me what to do now.</p>
