Error 0×8007064A installing Microsoft Security Essentials
I’ve been having error 0x8007064A when installing microsoft security essentials on my HP Laptop 8530W. The solution is to find the registry key:
[HKEY_CLASSES_ROOT\Installer\Products\HP_Preload_Dummy]
I don’t really know what this key does – but deleting your I was able to run the microsoft security essentials anti-virus product installer just fine.
If you’re in a country where microsoft security essentials is not avilable, the installer can be downloaded e.g. here: http://www.softpedia.com/get/Antivirus/Microsoft-Security-Essentials.shtml
