New Clean El Cap. Now "Pages cannot open because of a problem... this version OS X"
I finally decided to upgrade to El Cap.
At first I tried an upgrade install, but there were a lot of issues with constant beach balls... LOL
So I did a complete clean install. I have a simple set up with not a lot of extra apps.
I was using Mavericks and it was basically running well. It's just that some of my apps were upgrading but with minimum of El Cap.
I had to reinstall all my apps, app by app.
I copied over my iWork folder (Version 09) and didn't think about it right away. I don't use it as much as I used to after getting Nisus. Sometimes I used Keynote to view powerpoint files, etc.
Now, the first time I tried to use any of the iWork apps, it gives me this error "Pages cannot open because of a problem... it may not work with this version of OsX." And, the app just won't open. I have noticed MAS keeps telling me to install iWork 5, and I can't ignore update like others, so it just sits there. I have not installed it.
My most important question is how do I fix this using the Best Steps to get iWork '09 working again.
I am running El Cap 10.11.2. (this macmini came with Mavericks installed and I installed iWork '09)
I have my original iWork '09 install DVD 9.0.1.
I have the iWork 9.0.4 update (I also have the 9.3 update, but I had made a note to not use it! ?)
I have a clone of my Mavericks and iWork is working fine on it and my MacbookPro which is still Mavericks. (I like to take my time with OS upgrades!)
What are my best steps to get iWork 09 back to working?
Thanks so much for help!!
Mac mini, OS X El Capitan (10.11.2), 2 GHz Intel Core i7
