--- Comment #3 from Dan Kegel dank@kegel.com 2012-08-23 09:31:07 CDT --- Does the warning not happpen when you start office some other way?
That "IOPL not enabled" warning seems to have many causes. See bug 9422 and the replies to https://jeremy.visser.name/2008/08/iopl-not-enabled-with-visio-2003-in-wine/ If you still have trouble after trying the ideas there, ask again on forum.winehq.org (bugzilla is not a good place for this particular question).
