It does run on Windows, but you do have to build the package yourself.
It was done this way because the add-on is very hackish (altought effective).
This means that one is expected to have a fair knowledge of what is
going on (otherwise it easy for one to shoot oneself in the foot).
To minimize such incident, I only released the source for the package
assuming that one able to build the package should avoid pitfalls.
This was a temporary solution, better things are coming.

Currently, the creation of the AffyBatch object is a very memory hungry
step (way beyond what is required to have the object in memory).
What you can do is to ask someone with a lot of memory to create
the AffyBatch for you and save it as a R object. You just have to
fetch this R data file and load it.
 
Hopin' it helps,
