Not sure updates from HP Update are installing correctly

Question

Ever since I purchased my HP Officejet Pro 8620 in late November, I've been having issues installing updates.
I installed the drivers using an Administrator account; however, my day-to-day user account is not a member of the Administrators group.
Every few days, the UP Update app notifier appears on my screen. When I press Continue, the HP Update app loads. When I press the Next button the update downloads. Immediately after it downloads, I'm prompted for my PC's Administrator credentials. After I enter my credentials, the status immediately changes to "Installation failed" and the following message appears: "We noticed you had a problem with an update. Click here for an option to manually download and install or click 'Finish' to exit."
When I manually download and run the update, I'm prompted for my credentials but then nothing appears to happen. The download page says "In most cases, you will not see any message when the installation has finished." That appears to be the case here. However, within a few days, the update notifier appears again. So it would appear that the updates are not installing correctly.
Any suggestions on how to proceed?
