Question: Error Code 4 InDesign CS6

This worked for me! thank you!!!

Thank you!!! This worked!

Resetting InDesign preferences solved the issue for me.

1. Quit InDesign (if it is open)
2. Launch InDesign and press Command + Option + Control + Shift (Mac) or Control + Alt + Shift (Windows)
3. The prompt should appear asking you if you would like to delete the preferences file. Hit 'Yes' and after the InDesign opens try to open the file.

Note this will reset all your InDesign preferences.

Thanks so much - that really did the trick. I've backed-up that doc as well. Cheers

Worked for me!!!!! Thanks a lot!!!!

Thank you! This worked

Thanks, thanks a lot, it works! I was already crying at the thought of having to redo all the work!

I came across the same error, as well, and may have found a cause to some of the trouble.

In my case, quitting InDesign and restarting got me to open the file. When opening the file, there was a dialog alert regarding use of an InDesign that only works in CS6 and earlier. Once this dialog closed, all was OK.

Looks as if, in my case, it was due to this deprecated plugin. I deleted the layer with the offending plugin, and all looks OK  now.

I solved the problem with Clean my Mac 3. (On the Maintenance tab)

Brilliant app, I recommend it.

I just ran into this problem (Code 4) upon trying to open a file. After reading the thread, I closed Indesign and immediately reopened it. Then opened the file. Seems fine now.

Local file using Indesign CC 2015, latest release (as of 2/16/16).

Posting in case anyone else with CC 2015 has issues. Close ID, restart. Open file. Should be fine.

Just one users opinion and process.
