When I launch an activity in MyITLab, I receive a stub error message. The following information was found at http://247pearsoned.custhelp.com/app/answers/detail/a_id/6562/~/myitlab-2010%2F2007%3A-launch-assignment-failed-error-message
If you are receiving a stub error message similar to the one below
"C:\Users\UserName\AppData\Local\MICROS~1\Windows\TEMPOR~1\VIRTUA~1\C\PROGRA~1\myitlab\tait30.exe" -asgfile "assignment.ini" -cfgfile "config.ini" -crypt0 -debug0 -mutex1 -ignore""
when trying to launch an activity in MyITLab, you may need to update your browser security settings to allow you to access MyITLab without errors.
Internet Explorer recommended settings: http://247pearsoned.custhelp.com/app/answers/detail/a_id/241/related/1
Another suggestion is to have the user try Firefox. From experience, that works better than IE.
