You need to download the Drum Replcer installer (which contains both the 32 and 64 bit files) from your account as the CCC only installs the 64 bit version.
Once you run the installer (double click the file) you will be given an option to install the 32 bit version.
If you have already installed the 64 bit version you don't need to download the file again as it will be in your default CCC download folder. Otherwise, proceed to your account page and download from there.
