During HP printer driver installation, the computer prompts "Unable to install hardware" or "Access denied"

This error is mainly caused by Windows XP login permissions. Please perform the following operations to reset the system's administrative permissions:

At that time, my HP printer driver installed to the last step prompt "serious error occurred," almost tortured to death, did not expect to change the registry so, just fine.

Turn off the all-in-one that reported the error and disconnect the all-in-one from the computer.

Click "Start" in the lower left corner of the computer to open the "Run" window.

Enter "regedit" in the Run window and click the OK button.

Click HKEY_Local_Machine → Software, right-click Hewlett-Packard and select Permission.

In the Hewlett-Packard permissions window, click the Add button.

In the Select Users, Computers, or Groups window, click the Advanced button, and the menu in that window will expand.

In the expanded Select Users, Computers, or Groups window, click the Find Now button, and all users or groups that can be found will be displayed in the list below.

In the list of users or groups, select "Everyone" and click the "OK" button.

In the Everyone's Privileges window, make sure that Allow is checked after Full Control.

Click OK to save the modified options, then insert the driver CD and reinstall the driver.
