How to Remove Vmware Workstation From Ubuntu 13.04 for Good



VMWare Workstation doesn't ship in a deb, so it isn't registered in dpkg (which is why you can't find it in the software center). It does have an install and uninstall utility though.

To uninstall VMWare Workstation, you will need to run
vmware-installer --uninstall-product vmware-workstation

If you just run
vmware-installer

by itself, it will print all the options you have available. If you run
vmware-installer -l

It will print a list of all VMWare products you have installed.
