[ubuntu] Path problem installing VMWare tools

I found directions for installing VMWare tools but having problems with the path. I have the vmware tools extracted to my desktop and it is titled "vmware-tools-distrib" the instructions tell me to open an terminal and run this command:

cd Desktop/ vmware-tools-distrib (that worked fine)

Then I had to run this

sudo ./vmware-install.pl -d

I get this error:

"command not found"

I am running Ubuntu 12.04 LTS

What am I doing wrong? Thank you.
