--- Comment #9 from Olivier F. R. Dierick o.dierick@piezo-forte.be --- Confirming the bug.
Tested in Vista VM: on-line login successful. Tested Uplay (through Steam) in a 32-bit prefix set to Win XP: Uplay service unavailable. Tested Uplay (not Steam) in a 64-bit prefix set to Win 7: Uplay service unavailable.
Both test with plain wine 1.9.22 patched with the staged patch reference in bug 40271 (not wine-staging).
