Yep, you would have been sent an email but if you go to your account at the e-on website click on Your Orders, Download Links, Serial Numbers and Invoices link and then Vue 10.5 it will take you to a page where you can have the download link emailed to you.

With Vue Infinite 9.5 I didn't install it and when I came to install Vue Infinite 10 I had to install 9.5 first. E-on said they were going to fix this but I've no idea if Vue Infinite 11 will be the same or not.
