  1. There is a built in uninstall function now in the configs.

    If you comment out line 76 and uncomment line 79 in the authors example sc91_install.ps1 script you can re-run the script to remove an installation.

  2. Great guide! Needed to stand up a dev site asap. I didn’t have time to update my copy of SIFless for 9.1, so I used this to make sure I didn’t miss anything. Went flawlessly. Thanks for your efforts.

  3. Hello everyone! Thansk for the guide. The download link for the SiteCore XP Single 9.1 is not working. (even after login) Do you have an alternative link?
    Thank you.


  4. sc91_install.ps1 throws error.
    Install-SitecoreConfiguration : A parameter cannot be found that matches parameter name ‘InstallDirectory’.


      1. Its a great article. Helped me a lot installing sitecore 9.1. Just I was not able to understand “Install Directory” Parameter. Which I managed doing with XP0-SingleDeveloper.ps1. I made changes in XP-SingleDeveloper.ps1 and executed it. Rest run smoothly.
        Thank Viet.
