I have InDesign CS5.5, v.7.5. I'm trying to open a rather large file with lots of images, but it says "Please upgrade plugins/latest version", but when I tried to update it with download 7.5.1 through Adobe Patch Installer, it keeps saying "update is not applicable." Or it will almost install and then give me an error code.
InDesign will let me open certain files, but not the one I really need. It was working properly a few days ago.
This InDesign subscription I got was in Feb 2012 though my school. Help!
The error code is:
Error Code: U44M2P7
If you are using CS5.5 it isn't part of a subscription to creative cloud (hard to tell if that's what you mean), so you may have a newer version of InDesign installed as well (they are not mutually exclusive). That said, the last patch for CS5.5 was 7.5.3, but it doesn't really matter in this case. That warning indicates the files were saved in a newer version of InDesign and cannot be opened in CS5.5.
