SAPINST for Web AS ABAP 6.40?

I need to install the Web AS ABAP and J2EE 6.40 in order to start a prototype for a customer. I would greatly appreciate if someone can guide me to a location where I can get a SAPINST for the ABAP side. I've already installed the Web AS J2EE 6.40 from the SP6 location.

Thanks in advance, Andre
