Several days ago I uninstalled Norton Internet Security 2011 and installed AVG Internet Security 2012 on both my and my wife's laptops. Today I discovered an issue on hers necessitating uninstalling and reinstalling our HP printer software. Hers (running
Windows XP Media Center edition SP3) worked as expected. However, on mine (running Windows XP Pro SP3) the reinstallation of the HP software stopped and was unable to continue. The following message was displayed: "Windows Installer Registry - This registry
key does not exist and is required for installation to continue. Please ensure that the registry key exists and click retry to continue installation. Registry Key: HKEY_CLASSES_ROOT\CLSID\{000c101c-0000-0000-c000-000000000046}"
Two days ago I was able to install AVG so I'm suspecting something happened with the uninstallation of the HP software package.
So, I need help and recommendations on a fix. Hopefully, the fix will not be to reload the entire operating system. If absolutely necessary I can do that but it is not the preferred fix.
