Bobh,
You're welcome. Raptor is correct, by the way. Instructions for HP's software program removal were also included in that link I sent you toward the bottom of the page.
However, you stated...and I quote:
I tried to delete all HP programs but could not.
What did you try...you weren't very specific here.
I could not follow the instructions as I could not get the correct things to come up on my computer.
What things? Again...you're not being very specific. If you can't provide us with enough details...then we may not be able to help you.
Please...try to be as specific as possible.
