so i downloaded dotnetfw.exe then want to install it. But i always got an error

Error: Prerequisite programs are missing

Setup has detected that the following prerequisite programs are not installed:

Microsoft Windows Installer 3.0

You must first install these programs before Microsoft .Net Framework 2.0 can be installed

however, when i try to install MS Installer 3.1, unfortunately i got another error

KB893803v2 Setup Error

Setup has detected that the Service Pack version of this system is newer than the update you are applying.
