error when installing MSE

[Dieselman]

What are you talking about "all". How many programs were you using? What does the error exactly say? Are you using a firewall or any other security other then an anti virus? Are you sure you are not infected which can prohibit you from installing MSE?

I believe it could be an installer issue, not MSE itself, but the Microsoft Installer.

That's good advice about trying Microsoft's cleanup tool.
After you install it you should have a Windows Installer Cleanup Utility entry in your Start Menu, if I recall correctly.
If not, it's just a matter of navigating to your Program Files folder, finding the right folder, and running one of the two executables contained within.
I don't recall the filename so I can't say which of the two it is though.
Once run I know that MSE used to be listed as Microsoft Antimalware, but it may have been changed since then so look for Microsoft Security Essentials first.

Do you get an error code Ox80070643 in a dialog box with another message mentioning Windows Installer?
