error when try to Install VMware Tools in Ubuntu server

I faced a problem when I wanted to install VMware tools on Ubuntu Server 12.X, I have followed this article for how to setup vmware tools:
http://ghosttx.com/2012/03/how-to-install-vmware-tools-v4-on-ubuntu-11-10-server/

but after i run the command line to install the VMware tools I recieve error as follow:

A previous installation of VMware Tools has been detected.

The previous installation was made by the tar installer (version 4).

Keeping the tar4 installer database format.

You have a version of VMware Tools installed. Continuing this install will 
first uninstall the currently installed version. 
Do you wish to continue? (yes/no) [yes]

Error: Unable to execute "/usr/bin/vmware-uninstall-tools.pl.

Uninstall failed. Please correct the failure and re run the install.

Execution aborted.

 then i searched google for similar error, and found many solutions, but hte one worked for me is:
sudo rm -R /etc/vmware-tools
