Was your computer upgraded from Vista?
If so, perhaps
THIS
Even if you didn't upgrade the only solutions I have been able to find are remove and reinstall, so I suggest you get the removal tool to make sure all is cleared out and then retry.
I did find one other item for a different model HP which suggested it may have something to do with the users rights to an HP entry in the registry but the recommendation was give them rights which I think would not be a satisfactory solution for you.
Only other thing I could suggest is contacting HP support or post your issue on their forum.
