Select one file with right mouse click
on WIN to open with and select InDesign, open as default or all
on Mac > Info > Open with, select inDesign, change all files of that type.
I do not know whether you have a PC or Mac, but check to see what program is the default for opening PDFs.
Mine is Acrobat XI even if i export from Indesign.
Ask me if you are not sure how to do this.
No the issue is from within Indesign, the file is already open. I wish to export FROM Indesign a simple PDF. Its subsequently opening all pages as separate files in Photoshop.
The issue is NOT in InDesign. It’s in your operating system file associations.
I also have this problem and I did re-direct the file to open in acrobat instead of PS. I rebooted but it is still happening. Any thoughts?
