Error 0×8007064A When Installing MSE

Question:

When I try to install Microsoft Security Essentials (MSE) on my new Windows 7 laptop, a HP EliteBook 8530w notebook computer, BUT it fails with the following error:

0×8007064A

Can you help me install MSE?

Answer:

The HP EliteBook 8530w is a great laptop, but a few of them seem to present the error code 0×8007064A when trying to install MSE.

If you have REMOVED any other pre-loaded Anti Virus programs that may have come with the laptop, and then re-booted and STILL get the error 0×8007064A

The following registry key should be deleted:

[HKEY_CLASSES_ROOT\Installer\Products\HP_Preload_Dummy]

This should NOT be in the registry!

Hope this helps with the error 0×8007064A

Kind Regards
