try to reinstall the software HP provides registry key there is no error

Registry problem?

Several days ago, I uninstalled Norton Internet Security 2011 and installed AVG Internet Security 2012 on my and my portable computers wife. Today, I discovered a problem on his requiring the uninstallation and reinstallation of our HP printing software. Siena (running Windows XP Media Center edition SP3) worked as expected. However, on mine (running Windows XP Pro SP3) reinstalling the HP software stopped and could not continue. The following message appears: "Windows Installer Registry - this registry key does not exist and is required for the installation to continue. Please make sure that the registry key exists and click Retry to continue the installation. "Registry key: HKEY_CLASSES_ROOT\CLSID\ {000c101c-0000-0000-c000-000000000046}.

Two days ago I was able to install AVG so I suspect that something has happened with the HP software uninstalling.

So, I need help and recommendations on a fix. I hope that the fix is not to charge the full operating system. If absolutely necessary I can do but this is not the preferred solution.

First of all, the thread that I've referenced mentioned two key.  So when you checked, have you looked at a time

HKEY_CLASSES_ROOT\CLSID\ {000C101C-0000-0000-C000-000000000046}

and its main

HKEY_CLASSES_ROOT\CLSID\ {000C101C-0000-0000-C000-000000000046} \ProgId

If both of these keys have identical values as identified in the linked thread, run the reg file should have no effect one way or another.

Do a system restore to a point before you changed antivirus applications is an effort worth it.  You can not, however, use system restore to uninstall and reinstall the applications.  Before your doing a system restore, uninstall AVG.  Do the system restore.  Then re-install Norton (or, better, don't reinstall Norton; in this case, make sure that you are not connected to Internet).  See this FAQ--> http://bertk.mvps.org/html/tips.html#5

In fact, if you haven't already done so, you can run the tool to remove Norton, just to make sure that your problem is not caused by a few remaining remnant of Norton.  See https://www-secure.symantec.com/norton-support/jsp/help-solutions.jsp?lg=english&ct=united+states&docid=20080710133834EN&product=home&version=1&pvid=f-home

Microsoft KB article you mention addresses issues to uninstall applications.  As a general rule, Norton products should be removed with the removal of the above link tool.  Installs the printer may be deleted by following the directions here or here.  The Windows Installer Cleanup utility can be very useful.  Unfortunately, Microsoft has removed this utility of its download servers because it sometimes more removed he was supposed to.  It can always be obtained from http://majorgeeks.com/Windows_Installer_CleanUp_Utility_d4459.html is a similar tool (free) Revo Uninstaller.

Good luck.
