Hi Nancy
There is no direct replacement for Picture It 9 beyond modern photo editors such as Adobe Photoshop Elements, the built in Photos app in Windows 10 or the older discontinued Windows Photo Gallery 2012 which you can still download.
You can download and install it from the Windows Essentials 2012 suite:

or if you still prefer using Picture It! You could try obtaining a copy of its last successor, Digital Image Suite 10 and use the steps to install it:
