More typical Creative. Their driver/software situation has always been a mess. Anyway, I've got a file that looks like an Audigy 2 CD compressed. It has a folder in it that appears to contain the speaker setup program you want. Tell me how you want me to send it, and if you want the whole thing or what (it is a 119 MB .rar).
Oh yes, and apparently there is a way to mod the Audigy 2 drivers for use on Audigy and Live! sound cards. You don't get all of the features, and you don't get a crystal DAC obviously, but people say it helps things a lot. I dunno, I use a Fortissimo II so I've never had personal experience with it.
Edit: I'll try burning it and see if I can get it to run.
Edit 2.0: Whoops, my CDRs aren't here. I left them at a friend's house. But I did extract the speaker setup folder, and the installer runs and says creative speaker setup. So I can just .rar that up and AIM it to you or something. Wait, maybe I can just post it here... let me go compress it and see how big it is.
