10.5 artist to 13 artist

I upgraded from Cubase 10.5 artist to 13 artist, I now have two applications in my Windows 10 computer and two icons…one is 10.5 and the other 13…my question? should I delete the 10.5 artist from my computer.
THANKS

You can if you want, but there is no major reason to do so. The Cubase program is small and doesn’t consume much space. Many folks keep some old versions installed just in case - especially for older plug-ins and similar stuff. I currently have 4 older versions installed, the oldest being 7.5.

I spent hours searching for information. thank you I appreciate it very much.
