As an example, on a Windows 7 Host, for VMware Workstation 9.0.0 you'd need to create the following file at the following location containing the following information after the install and prior to launching VMware Workstation.
Filename: preferences.ini
Location: %APPDATA%\VMware
Example: C:\Users\WKZ\AppData\Roaming\VMware\preferences.ini
Content:
pref.eula.count = "2"
pref.eula0.product = "VMware Player"
pref.eula0.build = "812388"
pref.eula1.product = "VMware Workstation"
pref.eula1.build = "812388"
Note: For a different version change the pref.eula(n).build value to the appropriate value.
