Error code: 127 only under 64 bit Versions

[Filip Kaczorek]

Now I might be wrong but I think there was a change in Afterworks.dlu when FFX 1.1 was released, and so older versions of AB and DS wouldn't work.
Although the latest version of AB3.2c (I think) was recompiled for it.
Are you using an installer from the members area or some old that you had on a CD?
