New PC and struggling to get out of demo download with receipt

[Mobius]

Hi all, I recently upgraded my PC and downloaded OWM, but can't find where to put the receipt number to allow me to use it and upload the file I'm working on.
I've looked online everywhere and the advice I get doesn't match with what I'm trying to do
Thanks

It's been too long, so I don't remember the installation process. Other than looking for an existing thread, looks like you'll have to wait for another response.
