WindowsXP x64 Regional Settings Problem

[BabisSougias]

I have completed my unattended dvd for windows 32-bit and was giving a go to windows 64-bit.

I made the same steps but i have trouble with the regional options. In particual, if i choose greek on all options(with n-lite) the greek language is not even installed. Then, when i test my dvd office says the language i am trying to install is not supported by the OS and doesnt install :/.

Two things:

1) By comparing the two WINNT.SIF between the 32-bit DVD and the 64-bit one, they are identical(except the cd-key of course...). THe 32-bit version works great

2) When i install the 64-bit version unattended without regional specification or normally(non-unattended) the greek language is installed, although obviously not preselected.

The WINNT.SIF is this:
