Need to downgrade, where can I get the latest 7 install?

i need to downgrade from 8.5.2 to Cubase 7.5 because of the CPU spikes, plops/crackles.
Where can I find the latest 7.5 FULL installer?
Also will running this installer affect my 8.5 content?

Obviously on the Steinberg downloads pageā€¦

No, only the updates, in my Steinberg only 8.5.2
my bad, all the way at the bottom. Got it
