I've just purchased Designer Pro X17. My current version is Pro X11.

While in the middle of creating a new website and other projects...

When I install Pro X17, will it install over Pro X11?
If it does, are all my current settings/layouts going to be okay?

Or will Pro X17 install as a separate program?
If so, should I delete Pro X11 before I install, or afterwards?

Thanks,

Seamus
