I had to reinstall inDesign CS4 on a new computer, (Win10). It worked fine on my old PC (Win10). Now when I try to open documents that I created with CS4, I get an error message that I am missing several plugins. How do I update them? I've tried to update them through the program, but it says there are no updates. What do I need to do to be able to use this program?
CS4 is not supported under Windows 10 but that error message is indicative of trying to open a file created in a later version of InDesign.
