Here is one way to get the required fonts to make the worksheet equations appear correctly:
go to
http://www.dessci.com/en/dl/fonts/getfont.asp

place the two files:
TrueType font installer:   MTW4_TrueType.exe (773k)
    PostScript font installer:  MTW4_PostScript.exe (876k)
on your desktop.

You can find them here:
TrueType font installer:   MTW4_TrueType.exe (773k)
    PostScript font installer:  MTW4_PostScript.exe (876k)
