Hi.., Thank you for posting this query here. Please follow the below steps to resolve the issue.

You need to activate your built in administrator account. First you’ll need to open a command prompt in administrator mode by right-clicking and choosing “Run as administrator” (Type cmd in the start menu search text box. Right click on the cmd or command prompt listed under programs list and select run as administrator)

Now type the following command:

net user administrator /active:yes

You should see a message that the command completed successfully. Log out, and you’ll now see the Administrator account as a choice.

 

Click on and login as administrator. Now click here and download Revo uninstaller. You only need to download its freeware version. Install revo and launch it. You can see a list of all the programs installed on the system in revo. Select any instance of HP PhotoSmart program and uninstall it with the help of revo.

Restart the computer and login as Administrator again.

Now click here and download ccleaner. It is a freeware registry cleaner. Install and launch ccleaner. Click on the registry icon on the left side of ccleaner. Click on Scan for issues button. After completing the scan click on Fix selected issues button.

Restart the computer and login as administrator.

Install HP PhotoSmart again and check. If your CD does not contain windows 7 driver. please download it from here.


Reply me the result.
