Need guidance Downloading the RW Cursor Editor

So Yesterday I downloaded the RW Cursor Editor, but after I agreed with its TOS, my PC asked me "Do you want to allow this app to make changes to your device" Then I clicked cancel because I didn't want to let it change anything about my PC. Is there a way to fix this problem where I don't have to let it make changes to my PC? If it's possible. I want to use the Cursor Editor as long as it's safe from harming my laptop.
