The downloadable trial version of the VB application "Church Windows" installs fine... IF you first create a registry key to make it think IE6 is installed install the VB6 runtime install MFC40.DLL install MFC42.dll The latter three problems really aren't Wine's fault; the app leaves them out because most windows systems have them these days (really?). But the IE registry key is something Wine should maybe set by default. (See http://bugs.winehq.org/show_bug.cgi?id=3453) I even wrote a script to automate the download and install of all the prerequisites and the app itself; it's at http://kegel.com/wine/cw.sh.txt
Sadly, the app doesn't work too well once installed, but that's another story ( http://bugs.winehq.org/show_bug.cgi?id=3624 )
