Ironruby installation

A co-worker in Germany is trying to install IronRuby on Windows XP
SP3. The installer fails with:

“Dieses Installationspaket kann vom Windows Installer-Dienst nicht
installiert werden. Sie mussen ein Service Pack fur Windows
installieren, das eine neuere Version des Windows Installer-Diensts


“This installation package can not be installed by the Windows
Installer Service. You have to install a service pack for Windows
which contains a newer version for the Windows Installer Service”.

I had no such difficulty installing IronRuby on XP SP3 (English). Any
ideas what the remedy is?

I believe the installer is targeting v4.5 and I don’t know if that is
included in the service pack. The information about Windows installer
4.5 is here: Windows Installer 4.5 is available - Microsoft Support
