How to: Find DOpus 8 Registration after 9 Eval install

I installed version 9 in eval mode into a new folder. Now version 8 fails to start.

How do I find my version 8 registration code?

You can't install both 8 and 9 on the same machine. They conflict with each other.

If you reinstall Opus 8 it'll probably work fine without having to give it your licence details again. If not then there's a page at that lets you retrieve your licence details code via email.

OK. Thanks!
