WeiDU install fails

Struggling to get BG complete installed on my Windows 7 64-bit machine but WiuEI installation fails.

I've attached the (1.1Mb) debug file but the fatal line seems to be:

ERROR: Unix.Unix_error(20, "stat", "g:\\baldurs gate\\BG 1/characters/cleric.chr")

But my BG 1 installation folder doesn't have a /characters folder at all.

The /Data folder is there and seems to have everything it should have.

Should there be a /characters folder?  Can I import it from anywhere on the disks?

Any advice appreciated.

Thanks.
