Install both 12 & 13

I would like to install my backup 12 and reinstall 13, default. This would let me setup 13 as I lean more about it and still use 12.

Only one version can be installed at a time.

There's no need, either. Opus 13 can import your Opus 12 config, so you can continue using the config you were used to. Settings > Backup Restore lets you save/load/reset the config, if you want to switch between two configs or a custom config and the defaults.

I want a better understanding of Opus 13 than I have for 12. I Dont want any thing on 13 that is from my past. But I do want to use 12 when I have a need to get around. So I don't want to use my config of 12.

So I need my 12 as I always used it for, till I have 13 ready. Current ly I only have 13 installed over the top of 12. And I need 13 right out of the box.

My current goaled is using Opus 12 as I always have and 13 as out of the box. I have an LC for 2 copies.
