how do I restore 8.1.2 version of iPhoto from Time Machine

My iMac is Intel Core 2 Duo, with 2 partitions, 10.10..3 and 10.6.8. I downloaded iPhoto 9.6.1 on the 10.10.3 partition recently and now the photos don’t show the events, the dates are there but not the events.

When I just opened iPhotos with my 10.6.8 partition, it asked for a library which I picked and told me

"You can't open your current photo librart using this version of iPhoto. You have made changes to your photo library using a newer version of iPhoto. Please wuit and use the latest version of iPhoto.", of course the newer version of iPhoto is not compatible with 10.6.8.

So how do I restore iPhoto 8.1.2 and the appropriate photo libraries, etc from my Time Machine backup to my 10.6.8 partition, what files, libraries, preferences etc. would I delete before restoring.

Thanks,

Stan
