To remove VMD, you just have to remove the file "vmd" from where it was
installed (probably /usr/bin/vmd) and the directory /usr/lib/vmd.

This error means that you have installed the 64-bit version of VMD, but
only the 32-bit version of CUDA. As it looks that vmd_LINUXAMD64 was
running, you probably have installed the 32-bit version of CUDA on a
64-bit Linux. The best solution is to first remove the broken CUDA, and
then probably install a 64-bit CUDA.
