Hi,
I don't know where you read that it isn't part of the download, as it is actually part of your install.
Once you have installed VMware Workstation, the .iso files are all installed in the VMware installation folder.
Normally they are all installed at:
C:\Program Files (x86)\VMware\VMware Workstation
Just look for the .iso files down there.
You do not need to navigate there to attach the .iso files though as VMware Workstation either installs it for you (easy install), or you can install the VMware Tools via the menu.
Turn on the VM if not running already
From the menu "VM" select "Install VMware Tools"
Follow the steps in the VM.
If VMware Tools are already installed then it will say "Reinstall VMware Tools" as menu option instead.
