I bought parallels 12 but I have Macos 10.9.5

Hello,
I haven't check if parallels 12 was macos 10.9.5 compatible before I bought it, and it seems that it is not
Can I use parallels 11 (which is compatible with MacOs 10.9.5) with this purchase for now until I'll upgrade my macos ..?
I bought parallels product to try to play some games that are not available on the macos system.
I don't plan to upgrade my system (Mac) anytime soon for different reasons.
Thinking you in advance for your fast reply
Best regards
Charles
