If your Cubase 5.5.3 is installed on another computer, you’ll have to update your eLicenser Control Center license database on that computer, or else Cubase 5.5.3 wont be able to see your Cubase Pro 8.5 license.
To update the database on a supported OS, you can just download the eLicenser Control Center installer from this link and put it on a flash drive. It always comes with the latest license database: http://www.steinberg.net/en/company/technologies/elicenser.html
If you’re using an unsupported OS (XP or Vista/Mac OS X older than 10.7), you’ll have to connect that computer to the internet and run the eLicenser Control Center. This will update the license database.
I’m running W7 SP1.
My machine can not be conencted to internet (it runs in a white room).
I thought I had the latest elicencer driver package installed but I am not that sure.
So I’m d/ling it now.
Anyway that version was out after 8 for sure.
I have yet to test 8.5 itself (but that will wait, because
I have an awful lot of work to finish, and
each d/l of the 10 gb and some failed so far
and 3) of course I’m pretty sure reopning properly v5 projects in 8.5 will not be a piece of cake.
I’m even considering, with all horror stories here about spikes and audio drop out anf CPU consumptions in 8.5, using first 7.5. or 8.
I will start another topic, as I can"t open Cubase 8.5.
It crashes everytime over and over trying to use my old default VSTplugin path on the JBridged folder.
