Why won't an updated version of LabAuthor install on my computer?

Depending on the version of LabAuthor you are updating from and which operating system you are using, the installer may cancel without properly installing the new version of LabAuthor.  This is a rare event.  If this occurs, the best approach is to uninstall the previous version of LabAuthor and install LabAuthor from a newly downloaded copy of the LabTutor Teaching Suite.
