Agai, I have a problem with my CS5. My CS5 does't have a plugin: "SharedContent.IndesignPlugin". How can I install it, please?
Moving this discussion to the InDesign forum,
JesusHG do you receive this error when opening InDesign or opening a document?
You can't. You're trying to open an InDesign file created in a later version
of InDesign. Have whoever gave it to you export it to IDML.
