I really just need to know how to get it to open. I have created files in CC that now won't open, saying they were created in a newer version... which they weren't. i thought the remedy would be to download InDesign 2014, but i can't even get it to open on my computer. Any advise is welcomed.
Moving this discussion to the InDesign forum.
The CC installers often fail to set permissions correctly on the preference folders. Are you getting an error message to that effect?
If so, find the folders -- they're hidden so you need to set Explorer to show hidden files, then see Replace Your Preferences for the locations of the TWO folders you need to fix. Start at the Adobe level and make sure both your user and System have full control, and apply it to subfolders as well.
