I purchased 1Password for my Mac Pro (running 10.10.5) and iOS devices and it works great. However, when I try to install it on an older Mac running 10.7, the App Store says that it needs 10.10 to run. I have downloaded the legacy version for Lion but need the registration information to run. I have tried to get it through email using my iCloud account address with no luck. I would be happy to send a copy of the Apple receipt for the purchase.
