title: how to change from per user to all user installation?
body: <p>For our msi , we did not mention allusers property in existing releases. so by default it went as per user.</p>
  
  <p>Our customers installed the application using an admin user id and that admin left the company. So his user id is no more in valid condition.</p>
  
  <p>Now they are unable to migrate to newer version using another admin account (as it was installed as per user).</p>
  
  <p>Though we can change our msi to support allusers ,it would not work in migration (major upgrade). </p>
  
  <p>It seems like only when we give total new release where no existing release is supported we can fix the issue.</p>
  
  <p>Is there any other workaround there to mention even if the previous msi was per user ,it should be major upgraded now? </p>
  
  <p>We are using WIX 3.5 for our installation process.</p>
