I have Adobe CS6 and came across an issue when a fellow employee sent me a file. When attempting to open an .indd file in InDesign, a dialog box popped up stating "Cannot open because it was saved with a newer version of Adobe InDesign CS (8.1)" After noticing that I needed to update my CS version, I installed the updates and found that it now states "Cannot open because it was saved with a newer version of Adobe InDesign CS (10.1)" What does this mean? I've checked and I have InDesign version 8.0.2. and I don't have any more updates to install. Can anyone explain to me why this error is occurring and how to resolve this? I've received an .idml version of the file I'd like to open and that seems to work, however I'd like to resolve this issue so as to prevent this again. Any help is appreciated. Thanks.
Adobe Indesign CS (10.1) is the latest version of Indesign which is the 2014.1 release. As you saw exporting the 2014.1 file to .idml allows you to open it with CS6.
The only way to prevent it is to ask the other person to work in CS6 or for you to move to Creative Cloud.
