Okay, had to contact Customer service. I've got it now, but it seems to only install the 64 bit version.
Also, are Rapture and Dimension Pro not connected products?
Also, IIRC, Z3TA used to look first for its resources within the directory where the dll is located - it doesn't seem to do that anymore. I ABSOLUTELY hate having Cakewalk Content on the upper level of my main drive (and everywhere else it seems).
