--- Comment #7 from Bruno Jesus 00cpxxx@gmail.com --- Thank you. I don't really understand why windows exported the line twice, the second line is totally broken =)
As you can see the regedit exported version has \. If I change any of the \ to \ windows will also ignore the line and so will wine.
My current guess is that the software you used to export the registry has a bug.
