Need OS X v10.7 download

Question

There is an app that I would like to download, but get the message that it requires OS X v10.7.2.  I downloaded that version, but it wouldn't install.  I got the message that I needed to install OS X v10.7.  Unable to find version 10.7, I downloaded v10.7.1.  Same story: can't install without first installing v 10.7.  Where can I find that version to download?  Am I just out of luck forever because I didn't get the previous versions installed back when?

Answer 1

Where did you download 10.7.2?
If you didn't PURCHASE it from the App Store, then what you downloaded was the update, which requires at least 10.7, which you must PURCHASE 10.7 from the App Store.
If this is what it looked like when you downloaded it, then that is the update and won't install until you purchase Lion from the App Store:
This is the App Store page (except yours will have a price for Lion instead of "Installed")
You can get to the App Store by using the link in the Apple Menu:
