I'm a CC 2014 user on my Mac. But, we have a PC here in our department that has an old copy of CS4 InDesign on it. It doesn't really need anything newer than that, for the work that's done with it.
This PC just got a new hard drive. The old one crashed. So, actually, this new one is a solid state drive. So, it's nice and fast.
I've installed InDesign CS4 now twice. Whenever we open an ID document or template, we get a message saying that it can't open the file because plug-ins are missing. What can I do here?
You’re trying to open files created in a later version of InDesgin.
