InDesign 2017 & 2018 Stopped Working and Will Not Reinstall

[default1kmp5bignylc]

InDesign 2017 & 2018 stopped working, with a pop-up window that says "The applications seems to be damaged. Please uninstall and reinstall the application." After uninstalling the apps, and trying to reinstall them, I now get a window that says "The applications seems to be damaged. Please reinstall the application." I have done multiple restarts and also made sure that all unnecessary apps were shut down in the Activity Monitor. Our company does not have a dedicated IT person for Adobe/Mac so this has been dumped in my lap. Any ideas?

What is your version of macOS? A lot of problems come from letting the system get too new for the apps.

It's a con. 

They are trying to force everyone onto their scription based cloud set up.

Your reply, hearfelt no doubt, is complete nonsense, Ralph5. InDesign 2017 and InDesign 2018 -are- Creative Cloud (subscription) products. Where does that leave your theory?

Everything I said, word for word, is true. We still have clients that refuse to upgrade/update so I am currently handing off all of my 2017 & 2018 jobs to department colleagues. The one person on staff with extensive Adobe/Mac knowledge gave it his best shot but was unable to help.
