http://bugs.winehq.org/show_bug.cgi?id=22916 Summary: Program installs fine, but crashes on start Product: Wine Version: unspecified Platform: x86 URL: http://prv.tutor.com/install/netClassroom/Tutor.com%20 Classroom%20Setup.msi OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs(a)winehq.org ReportedBy: trevorolson(a)gmail.com After installation, when you try to open the program, it tries to open but crashes before it can open fully. In Windows a login screen appears. In WINE the entire program simply ceases to run. It just quits before the login screen appears. As a tester, you should know that the program should be working if you make it to the login screen. To fully test the program, you'd need a login and password though, which you need to work for tutor.com to have. Thanks for any assistance you can offer!
