Issue

When you try to open an Adobe InDesign CS3 document in a previous version of InDesign, InDesign returns the error message:

"Cannot Open File. InDesign Content Manager cannot open '[filename].indd.' Please upgrade your plug-ins to their latest versions or upgrade to the latest version of Adobe InDesign."

Reason

InDesign CS and CS2 cannot open native InDesign CS3 documents. The InDesign 4.0.5 update allows InDesign CS2 to open InDesign CS3 files that have been saved in .inx format.

Solution

Do one of the following solutions:

Solution 1: Install InDesign CS3.

Solution 2: Install the most recent InDesign CS2 update, and then open the document as an InDesign Interchange (.inx) file.

1. Install the Adobe Indesign CS2 4.05

Download the update from the Adobe website at www.adobe.com/support/downloads.

To open the document in InDesign CS2, you must first export the document from InDesign CS3 as an InDesign Interchange (.inx) file. Features that are specific to InDesign CS2 (for example, footnotes and object styles) may be modified or omitted when you open the INX file in InDesign CS 2

To export the file as an .inx file:

  1. Open the document in InDesign CS3
  2. Choose File > Export.
  3. Choose InDesign Interchange from the Save As Type or Format menu, and then click Save.
  4. Then open the file in Adobe Indesign CS2
