hmm... is it possible to use the Sonar custom install thingy to install certain elements (like R-Mix) at 32 bits? I do seem to recall that R-Mix does have a 32 bit version.
But that also brings up the issue that the included version of R-Mix is only supposed to work with Sonar so would it work with Pyro AC considering it's a Cake product?
I'm assuming no and frankly I'm neither smart nor patient enough to figure it out.
