There has been quite a bit of discussion about language problems in WET (appropriate acronym ).

I can confirm that WET is definitely anti-British (well anti-English(UK)).
I recently had to perform a refresh of my Win8 Pro X64 system, so I had the bright idea of using WET to create a transfer file so as to facilitate getting back all my apps etc..
Having done that I performed the refresh (making no changes to the language English(UK) or region settings (NZ)).
After the refresh I opened up the transfer file and to my dismay WET informed me that due to language differences it could not perform the full transfer.
So had to re-install all my apps.
