Hello CB-82,
If you have downloaded the full feature software you should have the HP Solution Center, if you did not create a shortcut on your desktop, it may still be in the HP folder. Please follow the steps listed below:
Go to your Start Menu> All programs> HP folder> HP Solution Center, you can then right click and create a shortcut to your desktop.
Please let me know if you were able to locate the Solution Center. I will watch for your reply.
Thanks in advance,
