Issue opening InDesign 2017 on old Mac

Question

So we have an old mac at work that uses 2017 InDesign. Its basically needing to stay old to let certian old programmes work that would be hugely expensive to upgrade. Its always worked with the same account I use for the programme here on my fairly new Mac which is quite up to date. I use InDesign 2025 .
 
The problem is the old mac had to restart and when it did the InDesign wont open. When we try (from cloud) it tells us we need to sign in, even though we are already signed in on that account (AI and PS both work) and when we click sign it it just says we have a trial which is not the case (its the same account I sign in with on my mac which works fine). So is asking us to pay for a new account.

Any ideas? We have used it on both mac for a long time now. Im guessing its the old version is causing issues? maybe unsupported now?

Try these, one at a time, in order:Sign out of your Creative Cloud account and sign back in. Install the latest InDesign and start it, quit, and try to open the older version.Use Adobe CC Cleaner to remove your Adobe ID Credentials. (Don't remove the software.)
