--- Comment #4 from Sebastian Lackner sebastian@fds-team.de --- I have just updated the patchset, and added threadpool wait object support.
With that fixed ApexDC 1.6.0 starts as expected even when the wineprefix is set to Vista. It is not really a good test though, because the functions are not really called very often. When more apps expect CreateThreadpoolWait / ntdll.TpAllocWait it probably makes sense to open a new follow-up bug report for that.
BTW: The problem also exists in the 32-bit version, and is not really win64 specific.
