rundll32.exe error when setting up SQL Server Native Client

[genericUser]

Hello, I am trying to get a Windows program to run on Mac OSX computers through Wine. I have installed Wine through MacPorts, winetricks, and followed this guide as far as getting ODBC connection to work http://wiki.winehq.org/NativeOdbc .

When I go to configure the SQL Server Native Client 10.0, I get an error that says "the program rundll32.exe has encountered serious error crash:. I can configure the other connection types without this error, but as soon as I even try to create a Native Client 10.0 connection, the program crashes.

Thank you for any advice!
