Install purchased Dorico Elements 4 and Dorico Pro Trail at the same time

Can I install a Dorico Pro Trail alongside a purchased and already installed version of Dorico Elements 4? I would like to take part in an online training course and for this I need a Dorico 4 Trail version. Is that easily possible?

I believe you’ve asked this same question in the German-language Dorico forum as well, @Detgyver, and my colleague Stefan has answered you there.
