Can I delete 3.5 having upgraded to 4?

Apologies in advance for a very basic question. I’m doing a spring clean on my Windows 10 PC and uninstalling any unused programs. I see Dorico 3,5 occupies 407 MB - can I uninstall this now that I have Dorico 4 up and running? Or is it needed to support Dorico 4?

3.5 is not needed to support Dorico 4. I left it on my machine for a while however because in the early versions of Dorico 4 you could experience some bugs and using 3.5 was a fine fallback. Meanwhile I have deleted 3.5 from my machine since Dorico 4 runs smoothly.

Many thanks - just the answer I needed.
