Lost FMP7 disc; can't install upgrade

[Rank Beginner]

In 2006, I upgraded to FMP 8.5v1 on my desktop G5 Mac.

I need to run the database on a new-to-me laptop, but can't install the software because I cannot find the original FMP 7 disc, and the 8.5 disc is an upgrade, so won't install if it can't find the previous version or at least a product key from the FMP 7 disc.

Does anyone know of a solution?

Thank you!

Can you just make a copy of the FMP 7 application folder adn copy that onto the new machine?
