Hello jrcatt,
Welcome to the HP Support Forums! :) I see you are getting an error when trying to use Solution Center with your HP Officejet 7310, it is telling you that software is missing. Did this computer come pre installed with Windows 7, or did you upgrade the operating system?
I know you have tried uninstalling and reinstalling the software I would like you to continue with the following the steps below:
Step one: Clear temp directory
- Type %temp% in the run or search for programs and files field
- Highlight all the files in this folder, and then press the delete key to delete. If you get a message that the file is in use you will need to skip this file(s).
- Continue with Step 2 below
Step two: Downloaded and extracted to your system:
1. Download the full feature software and drivers
2. Once the download is finished double click on the file to extract the software.
3. When the installation window opens press the cancel button to stop the installation
4. Type %temp% in the run or search for programs and files field
5. Look for, and open the folder starting with 7z (Example: 7zS2356)
6. Right click on the folder, and select Copy
7. Close that window, and all your open windows, and then in the middle of the desktop right click your mouse, and select Paste. This will move the 7z folder to your desktop.
8. Open the 7z folder you just copied to your desktop
9. Open folder Util
10. Open folder CCC
11. Run the uninstall_L4
12. When the uninstall has completed restart the computer
13. Run Disk cleanup from Accessories\ System Tools folder under all programs
14. Download and install the latest version of Adobe flash player

15. Open the 7z folder, and then double click on the Setup.exe file which will be toward the bottom of the open window. Follow the on screen instructions to reinstall your printer.
Please let me know the outcome.
Thanks,
