Downgrade Person Environment Version

Downgrade Person Environment Version

  
Hello,

I'm startind the developer course but my computer does not have compatibility with Service Studio 9, so I have to use version 8. But when I try to connect to my personal environment, there's an error saying my ServiceStudio (version  8) is not compatible with my personal environment (version 9). How can I downgrade my personal environment's version, since it's not an option to have Service Studio 9 on my computer?
Thank you in advance

Never mind, I managed to install the Developmetn Environment 9.0.0.23
Thank you anyway!
