title: How to delete some files after msi installation is completed
body: <p>I have a custom screen step displaying checkbox options for web.config specific to each environments (DEVINT, QA, Stage,Prod) as part of MSI installation.</p>
  
  <p>Once the user selects QA as option then the web.qa.config file is renamed to web.config file 
  After the complete installation, I see that there are other web.config files ( web.DEVINT.config,web.stage.config,web.prod.config) still present in the folder.</p>
  
  <p>I want to remove the other web.config files web.DEVINT.config,web.stage.config,web.prod.config
  after the installation is completed.</p>
  
  <p>Can anyone help me to resolve this issue.</p>
  
  <p>Thanks &amp; Regards,
