How can I stiop HP pop up every time I start my MacBook?

Any idea how to get the HP set up assistant to stop popping up?

I don't think there is a way to stop it.

We have this on some Macs and Windows units, we have spent days on this with no luck.

You have hid the application, but have you erased it from startup applications? Go into Settings->Accounts->Login Items->and then instead of checking the Hide option, highlight the program and click the minus icon. Hopefully this will fix your problem.

If it's located in the Utilities folder located inside the Applications forlder, and since you no longer have need for the setup assistant, simply delete it. If later you should need it, you'll still have the disc to get it back.

Or am I missing something here? I'm guessing that it usually deletes itself after being used (to achieve a successful setup) - since you only performed setup once, (that's all it needs - I only setup each of my two HP printers once) that copy deleted itself. The duplicate setup assistant on the other Mac would self-delete also, if used. Delete it yourself, it's a self-contained file.
