title: Exception deserializing the package error when executing SSIS package
body: <p>I've just installed Visual studio Professional 2015 on a Microsoft 2019 Server with the following tools:</p>
  
  <ul>
  <li>VS update 3</li>
  <li>Sql Server Data Tools</li>
  <li>BI Developer Extensions for Visual Studio 2015</li>
  <li>Apex tools</li>
  <li>ZappySys SSIS tools</li>
  </ul>
  
  <p>When I go to run an SSIS package that works on other machines I get the following error message:</p>

  <p>I've repaired SQL Server Data tools and Visual studio itself with no luck. Any suggestions?</p>
