Not possible to install Trados Studio 2014 on a PC with Trados 2007?

Hi all! 

I'm trying to install Trados Studio 2014 and I get an error message saying it's not possible to install it on a PC with Trados 2007. Do I really have to delete Trados 2007 from my PC to install Studio 2014?

Many thanks in advance!
