Reply To: InDesign won’t launch

No, if you see that message and click OK, then you do not need to keep holding down the keys. No need to do it multiple times; if it doesn’t work the first time, it won’t work.

You can try launching the app from a different account (like a guest account) on the same computer to see if that works.

It could be a wide range of things, including what fonts you have installed. (Corrupted fonts have been known to take down the app.)

But I do wonder if you’re going to need to re-install the app. Ouch.
