Envy Photo 7155 Driver is Unavailable

[HawksandHandsaw]

I have just purchased the HP Envy Photo 7155. During initial setup I had no trouble installing ink cartridges, connecting the printer to my wifi network, or setting it up for web-enabled printing. I am also able to add the printer to my PC's list of devices but this printer has the message "Driver is unavailable" beneath it. I have run HP's installation software multiple times. Each time it appears to finish successfully. I have attempted to uninstall and re-install the printer to no avail. I have also attemtped to add the printer via Windows 10's prompt in the device manager and add the drivers manually in Print Server Properties. No luck so far...and my frustration is growing...

Any and all help is welcome and appreciated!

**Be aware that if you have other printers installed on your PC, those will need to be reinstalled too once completing these steps.

5. Browse to c:\Windows\System32\spool\drivers.

     Note: if any of these folders fail to rename reboot your PC and then Continue following the steps starting from Step 4...
6. Restart your computer.

Please let me know the results,

Same issue. Didn't work for either of my laptops and both have the exact same issue.  Still can't install the drivers and connect my printer.
