How to Upgrade from Cubase 7.0.7 to 7.5?

Can someone please tell me how to Upgrade from Cubase 7.0.7 to 7.5? For the life of me I can’t seem to find a link. All I see are upgrades to 8.0.
The reason I want to upgrade to 7.5 is for the purpose of being able to export multiple tracks at once. Here is the previous discussion regarding the issue. As well I use a Mac so Meap will not work for me.

Many thanks , Jeff

Cubase 7.5 is no longer for sale in the Steinberg Online Shop. Cubase is on version 8 now. You can try to find an upgrade online or buy the Cubase 8 upgrade, which will allow you to use Cubase 7.5.
