--- Comment #2 from joaopa jeremielapuree@yahoo.fr 2009-08-06 12:09:56 --- The key ef985e71-d5c7-42d4-ba4d-2d073e2e96f4 is related to dsdmo.
So, I put a native dsdmo.dll in my .wine/system32 folder and now everything is OK.
Unfortunately, I can not find any documentation for this dll to try to begin to implement the missing stuff.
