Security Essentials error code 0x80070645

I have been through all the theads about this subject, and I have done all the things recommended.  I still cannot install MSE.  And the installation does not create an errorlog (in Docs and Settings/**** as described in one of the threads).

I tired to install AVG, - that went OK, and then I uninstalled it again and ran the independant removal tool afterward, so everythings should be removed.  Still the same result. 

What I do not understand is that there is no log showing what is wrong.  Please help

I am using XP SP3 completedly updated (according to windows update)
