The last article, however, refers to the following error message:
Error 1603: Fatal error during installation
However, I have the above error with error code 0x8007064A. Two XP computers can not install the Security Essentials killed croak. Installation fails after successful validation and clicking the button immediately with this error message. I've tried all the tips from the article at the top to no avail, I have no laptop. Per Google there are many others who have this problem too. A log file is at me not even created. I even tried a tip where you used to successfully install a different PC, but that does not work. The two XP computers do otherwise no problems, everything else can be installed far more, with updates .Net 1.1 there was ever trouble. Perhaps MS could deal with the problem once and modify the product so that it can be installed on all computers and spends at least a more helpful error message.
