Greetings Experts,

When running the installer: rewrite_1.1_x86_rtw.msi
I get the following error message:

This installation package cannot be installed by the Windows Installer service. You must install a Windows service pack that contains a newer version of the Windows Installer service.

I have checked and I'm fully up-to-date on Windows Update.

I'm running Windows Server 2003 Web Edition, SP2.

Which service pack do I need to install so that I can install URL Rewrite?
