@nagaflas: it's not the source which has not enough space but the destination. Copying the source anywhere does not help, you have to change the destination.
@ckillerh3: either make the drive full so that only less then 2GB are free, or remove the space check from the installer script, or use a HDF of less than 2GB.
Or install to RAM:, copy the result to your HDD and change all references to the WW directory (IIRC there is only one ENV variable which points to WWFonts).
Bye,
Thomas
