Make sure you have one of the required complers in your executable path. See
for compilers.

If you tried to re-link Natural using the Natural installation, there should be a file called NATv611xxInst.dbg in the directory from where you started the installation (via setup.ux, usually the CD). Have a look into this file. It is a protocol of the installation. May be you get some more info from there.
