The 7310xi HP all in One software CD from HP is total garbage. First check hp.com for any new software.
If the installation after downloading from HP appears to hang or never finish the installation just hung at the end leading the user to think it was unsuccessful . This can drive most people mad because they think the software and drivers were never loaded but they are.
Kill the installation after waiting about 5 minutes at step 8/8, Check the Printer and Scanner, they’re probably fine.
