LN, yes he did have iPhoto on his old hard drive but that was failing and taken out of his computer. The new drive with Yosemite doesn't have iPhoto on it. His old drive was over 10 years old and back then, iPhoto came with the older software. So he didn't purchase it from the App store. He did check his purchases from the APP store and iPhoto was not there.
I trashed my iPhoto after saving it on my external drive and am downloading it all over again from the App store. I will then try to send it via MAILBIGFILE to my brother with the hopes he can download it and use it. All he needs is iPhoto for Helicon Focus to work again.
I sure hope this works. With my slow internet connection it's taking over an hour to download and will take many times that to upload onto MAILBIGFILE.
Thanks for your response.
