--- Comment #4 from Kai Blin kai.blin@gmail.com 2008-07-28 13:06:40 --- I'm pretty sure quicken needs SCHANNEL (everybody else calls this SSL) support to register. Wine does not supply an SCHANNEL implementation so far.
As far as I know there has been some effort in getting the Windows schannel.dll to load in Wine and provide SCHANNEL, but I'm not sure if that's working yet.
On a quick search, there's a patch attached to http://www.winehq.org/pipermail/wine-patches/2008-June/056347.html that should allow to do this, perhaps you could try that.
