The "Norton" consumer and "Symantec" enterprise product lines are quite different, and "Norton Ghost" is, despite the mis-use of the Ghost brand name, not Ghost nor anything remotely related to it (it's a "lite" consumer version of the product sold as Backup Exec System Recovery). Since you purchased it thinking it is a version of genuine Ghost, you should return it for a refund (Symantec has a 60-day refund policy for Norton-branded consumer products detailed
at this page).
> I can somehow get copy of Ghost 11.0 but is it legal ?
No, it isn't. In fact, almost all third-party discussion of "Ghost 11.0" is actually referring to illegal, unlicensed use of the product.
There is no such product as Ghost 11.0; there is a genuine Ghost executable which identifies itself internally as version 11.0, but it was only ever sold as part of Ghost Solution Suite 2.0 and can only be legally used in conjunction with a suitable Ghost Solution Suite client license (or the single-use-only manufacturing licenses we sell to computer resellers).
