Hi there everyone. I am using a Macbook Pro 16 gigs 2.8 Ghz 1 terabyte SSD and Mavericks OSX 10.9.5. I have Parallels Desktop 8 and Windows 7. I would like to update Parallels to a newer version but I need to stay on Windows 7 for the software I run inside it. Can I update Parallels without having to reinstall or move from Windows 7? In other words is it possible to update from Parallels 8 to a newer version while not changing the Windows 7 emulation at all. And if I update to a newer version of OSX what versions of Paralells are compatible (I know I am behind with both OSX 10.10 and OSX 10.11 and even OSX 10.12 available). Thanks for any help and advice with this. I am worried about destrying the current perfectly good operating environment I have for Windows 7 using Parallels Desktop 8. Best regards Julian
