In Captivate 9 | Use of the Levenim MT font (doesn't show up on some computers)

In Capitvate 9 I created a responsive elearning course, I have used the Levenim MT font throughout my course.  There are a few people when viewing the font doesn't show correctly.  It actually goes into a serif font vs. the sans serif font that I used throughout the course (Levenim MT).  Is there something that can be done so that the viewer always sees the correct font when using any computer?  And, if I have to change the Levenim MT font throughout the whole course - can you provide me instructions on how to do so - the quickest and easiest way???  Thanks
