I just got a new machine because of failed hard drive - when I installed Indesign - it gives this startup alert and then does not work - "Adobe InDesign cannot load the Digital Publishing UI.InDesignPlugin plug-in. The Digital Publishing UI.InDesignPlugin plug-in requires the 11.2 version of InDesign. Please contact the vendor to get a compatible version of Digital Publishing UI. InDesignPlugin. Show this alert again?" Any idea why these wouldn't install with the software if it is so necessary it can't run without it. Has anyone else had this problem?
If you installed the latest version of InDesign CC 2015, it won't work with the Digital Publishing plugin. CC2015 has moved to the Digital Publishing Solutions workflow. You would have to install CC 2014.
But to read about changes in the workflows see this posting:
