Hi, when I try to install CHAID using - install.packages("CHAID", repos="http://R-Forge.R-project.org"), it is throwing me the following error:

DLL 'mvtnorm' not found: maybe not installed for this architecture?

It seems you are missing the mvtnorm package, try installing it first.

install.packages("mvtnorm")

Also, you have the 32-bit R version installed, if you don't actually need this version (which is rare this days), I recommend you to uninstall it to avoid having to compile packages for two architectures unnecessarily.
