The tools are avaliable in the installer that is offered at http://www.vmware.com/downloads/.
The tools iso files are extracted with for example
VMware-workstation-full-8.0.0-471780.exe /e tmp
tools-windows-8.8.0.exe /e tmp
msiexec /a tools-windows.msi /qb TARGETDIR=C:\...\tmp
7-Zip can extract the msi file too (but not the custom installer).
