Free Trial

Hello,

I'm currently using Studio 2017 Starter and would like to start the free trial for Studio 2019. On the trial web page it says the trial software won't work if I have another version of Trados on my desktop. Does that mean I need to uninstall Starter before beginning the trial? If so, will I be able to get it back again if I decide not to buy the full version at the end of the trial?

Thanks for your help.
