I just received an InDesign CS5.5 file saved as an .idml file. I cannot open this file in CS5. I still get the message that I need to upgrade half a version to
5.5. I am an instructor teaching InDesign CS5. The school I work for, purchased a license for CS5 last year, it is obsolete with the half version.
Hi Heidi, is your CS5 updated to the latest version?
Are you sure the file was actually exported to .idml, and the user didn't just change the file extension?
Thanks! That did the trick. Instead of Exporting, they were Saving As an idml file.
