Yes but I believe it has to be at least SP2 for R2.
It doesn't seem to say that, but I'd suggest you log a support call with your local support team just to be sure
we have raised a call, reference 00533149, but it seems to be quicker to get a response through the discussion forum !
We are getting an error, attached, that seems to be telling us that we have a conflict between 64 bit IIS and 32 bit application. Are we doing something wrong ?

Does the install actually fail? I've seen those black boxes pop up with stuff before now and they can sometimes be just warnings. The 'formal' statement on 2003 R2 is ...
Microsoft Windows 2003 Server SP2 or later (x86, x64)
Microsoft Windows 2003 R2 Server (x86, x64)
So if you have 2003 R2 you shouldn't use any SP if you want a supported system. If you have 2003, then you must use SP2 or later.
I know I'm stating the obvious, but at least you know where you stand.
