Sorry, it's my mistake. I write the installer to check dw.exe for EU version but it should be ds9dw.exe.
Please try this one, you have to choose correct folder yourself:
[Mega Upload link removed, as Microsoft incorrectly thinks it is infriging Windows - but as Megaupload is dead, no harm done]
Sorry for any inconvenience encountered.
I'll explain how this patcher works:
First it will extract official US/EU/DE patch, and patch your DW to 1.04.
Then it will extract hex-edited ds9dw.exe and ddra2.dll wrapper to overwrite original file. DW should work after it finished.
