Uninstall package: error code 2

When I try to remove the package in a terminal window, I get this error message:
sub-process /usr/bin/dpkg returned an error code (1)

gksudo nautilus

navigate to /usr/bin/dpkg/info
remove via the search-option: 3dxware

close nautilus
sudo apt-get update

of: sudo dpkg --remove --force-remove-reinstreq naam-van-het-pakket

Thank you for the answer. Your first solution does not work for me, because I don't have the folder "dpkg" on that location.
Your second solution gives the same error:

sudo dpkg --remove --force-remove-reinstreq 3dxware

Thanks leoquant, that solved my question.
