But just to be on the safe side, I'd suggest creating a restore point on your system before installing.
I prefer to make an image, which I did

System Restore doesn't provide 100% restoration it only covers certain files and areas. Disk Imaging makes an exact copy of the Disk or Partition, etc. for me it really is the only solution when you want a robust Backup and Recovery strategy.
I'm sure you don't create an image before every program update. I know I don't and on occasion,
the system restore point has come in handy. Not perfect but handy.
I do for some; my usual practice is a weekly image backup and daily data backups (sometimes 2-3 times) for more volatile data, documents, spreadsheets, emails, bookmarks, etc.
