Are you installing InDesign CC 2017 for the first time? Or, are you updating to InDesign CC 2017?
What operating system are you running (exactly)?

I have been able to successfully update and start both Photoshop and Illustrator, but when I initiate InDesign
If you had a previous version of InDesign installed, try deleting your preferences. There are two different ways, both described here. If they first one doesn't work, try the second.
You can also uninstall, run the CC cleaner tool and then reinstall.
Updating from CC 2015, and running OS X El Capitan Version 10.11.5.
Hi Steve she is upgrading the version she has. The operating system is

What Barb said above: Restore (delete) your preferences.
