I have this message pop up when I attempt to open an idml file generated with Adobe InDesign 2018 13.0.1 in Creative suite 6:
"Cannot open the file ' File Name.idml'. Adobe InDesign may not support the file format, a plug-in that supports the file format may be missing, or the file may be open in another application."
I have reinstalled Indesign to ensure all plugins are present and installed, turned off all fonts, checked that only one version of the file is open and closed all other Adobe and non-adobe applications to ensure the file is not open in any other applications.
Interestingly, idml files created before the update open fine, with all data as expected.
