Studio 2019 new license activated, Multiterm crash

 Studio 2019 new license activated, there is still Studio 2017. Should I remove it? There is only Multiterm 2017 showing "Remove suite of products". I am not allowed to repair it. When working in Studio 2019 and implementing new words, Multiterm and then Studio crashed both, several times. Studio without Multiterm is not useful, what to do?
