No, there is no way to download the free add-in that accompanies XL.
It has to be installed from the installation CD.

I'm writing an application for Excel that would require users have Solver
installed on their computer. Can I provide a hyperlink to download the
add-in over the web? Many users may have lost their Office disk or may not
have it handy.
