I have cc on my home computer, and tried to open a cc InDesign file from my work, but it said I need a newer version of InDesign. I don't understand. I just updated my cc InDesign, Photoshop, and Illustrator apps. Why can't I open this file? I thought paying for this service would keep me "up to date." Does anyone know the answer?
Most likely at home you have Indesign CC and at work Indesign CC 2014. What version do you see on Help/About Indesign? You can check the file on Bridge/File Properties to see the version it was created with.
As Ellis stated there is version mismatch. Please check how many versions of Indesign installed on your machine , if there are two CC and CC2014, then try to launch CC2014 and try to open the file.
If you do not see CC2014 then you can open Adobe Creative Cloud App and install CC2014.If you update or install CC 2014, it will not replace CC to CC 2014 but you will have 2 versions of the same .
