Clients are asking for a downgraded InDesign file. I have CC and I know I can save as IDML, but they do not want an IDML. Is there another save option that I am missing? There is a language issue (Japanese/English) and I think that is causing a lot of problems, but Adobe should be the same everywhere. They are insisting, however, for a "downgraded INDD file". Help please. I have sent them the IDMLs, but they don't want that.
You need to get some clarification.
The only way to save an earlier version would be to open the .idml in the earlier version and save as .indd, but you'd need to have the earlier version installed.
