Invalid Font Error - Font 'Arial' doesn't support style 'Regular'

[rmoss]

When you start the VisualTour Studio software, you might encounter an error saying:
Invalid Font. Default will be used

followed by another error saying:

We're sorry but an unexpected error has occurred.
Unable to load settings:
Font 'Arial' doesn't support style 'Regular'

This error occurs when something is wrong with Arial or one of the default system fonts. To fix the problem, just run the following file:
http://www.visualtour.com/downloads/fonterror.exe

It will re-register the Arial and Sans Serif typefaces used by the VisualTour Studio software.
