Hello. When I want to install the new XVM, should I delete the old one first and then download and install the new one or I don't need to delete old one? Beacuse, I downloaded the new one 6.6.2 and installed it, but it didn't work because I'm in the Europe, so I downloaded the old one and installed it but didn't delete 6.6.2... Is that ok?
