Hi,
you can install vmware tools after guest operating system. Normaly, installing the vmware tools is easy process.
I really don't like use the "easy install" feature.
Check this vmware's KB abount installing vmware tools:
You should install the build-essential package in the Ubuntu virtual machine, to be able to install smoothly the vmware tools.
Hope this helps you Image may be NSFW.
Clik here to view.
Regards,
Pablo
