Ever since I updated to InDesign CC 14, and uninstalled CS6 and CC, the thumbnails of all my saved files are now blank. Also when I click on file in Folder to open it, a dialogue box with the following message pops up:
"This file does not have a program associated with it for performing the action. Please install a program or, if one is already installed, create an association in the Default Programs control panel."
Does anyone have a solution to this problem?
Sounds like you are running under Windows.
InDesign has had a bug for over 10 years (if not longer) wherein if you install a new version and then delete any previous version, you lose file associations. A fix is supposed in the works.
To repair your file associations you must total uninstall InDesign 10 (CC 2014) and then reinstall it.
Yes, this is a royal pain in the tuchas!
