This would be a really good thing to note in the pre-requisites section of the installation document.

Is the only option to enable 32 bit compatibility? Is there a way to also provide .Net in 32 bit mode on the server? Part of the KB article reads:

Is there another way to install .Net other than the default for 64 bit?
