title: Using Excel on Azure
body: <p>I am trying to create excel files on Azure using Excel interop but I get the following message:</p>
  
  <p>"Retrieving the COM class factory for component with CLSID {XXX} failed due to the following error: 80040154"</p>
  
  <p>I understood I must have excel on the server to solve this issue.</p>
  
  <p>Does anyone knows how do I install excel on azure?</p>
