Hey pmonty,
Ok, so with the last steps not working, the next couple steps will be to test if we can get the software installed a different way.
First you will need to test the built in scan software/drivers of the notebook. To do this you can use two different options. One is HP Scan. This app should be pre-installed with all the other apps on your computer. The second option is Paint. To use Paint, all you need to do is open the software, and then under file select From scanner or camera. Are you able to scan with either of these methods?
The next test will find out if you can install the printer on another User Account. I have included the steps below, if you need them.
1. From the Start screen type Control Panel
2. Open the Control Panel
3. Open User Accounts
4. Click on Manage another account
5. Click on Ass a new user in PC settings
Then follow through the steps for creating a new user. Once the new user is created, you will need to be signed into this profile. After you are signed into the new profile, try downloading, and installing the full featured software of the printer.
Are you able to install the software successfully?
Looking forward to your answers. :)
