File associations are an OS function, so to fix it you need to do it through the OS.
It's on PC not Mac...but thanks
I wish this were an answer, but in support, I have the same problem with InDesign .indd files. No matter how I try to re-associate the files on my PC, the new InDesign CC 2015 .exe extension will not register in the Windows 7 OS 'Open with' dialog box even after browsing to the program file and identifying the application. It just will not identify InDesign CC 2015.
I just re-installed InDesign CC 2014; .indd files are now associated with that application. Still if I want to use 2015, I have to open from within the new version or drag and drop the file into it.
Note: I had similar issues with .psd & .jpg files that I wanted associated with Photoshop CC 2015. I resolved that issue by right-clicking the Photoshop icon and selecting 'Run as administrator', thereby permitting the program to 'make changes to my computer'. Ditto Illustrator CC 2015.
This did not resolve the issue for InDesign CC 2015.
Good luck & best regards.
It's still an OS (in this case Windows) function. You can, in theory, hack the registry to make things work properly, but I wouldn't recommend it for any but the most advanced Windows user. A failed file association here usually means a non-fatal failed install, and often the easiest way to fix it is to uninstall, run the cleaner tool (CS Cleaner Tool for installation problems | CCM, CS6, CS5.5, CS5, CS4, CS3) and reinstall.
Thank you for the follow-up, Peter.
Yes, exactly. (And I've noted some discussion of further issues with the clean-up tool. Oh well.)
It often helps to run MSconfig and turn off all non-essential startup programs and services before running the installer.
Thank you. That's good to know. When I have time, I will try a clean reinstall.
In the meantime, I continue to love my Adobe products and use them everyday.
