From Microsoft Social's forum:
I would suggest you to follow these
steps at the time of installing and
check if the issue is resolved.
• If you install a TrueType font with
exactly the same name as a PostScript
font on the same computer, Windows
won't know which one to access, which
could result in a font type being
altered. To avoid this, don't install
different types of fonts with the same
name.
• If a program is open when you
install a font, the program might not
register the font. Try closing and
then reopening the program.
• Some fonts require that you install
two files in the same folder: A bitmap
file for the on-screen font and an
outline file for the printer. If a
bitmap file and an outline file are
available for a particular font, make
sure you install both files.

I would also suggest you to right
click on the setup file of the program
and choose Run as Administrator to
install and check if the issue is
resolved.
You may also refer the below
mentioned link.
If this does not help then, I would
suggest you to copy the capture it.ttf
files and paste them to fonts folder
and check if the issue is resolved.
Some side-notes:
You probably first have to unzip the font, else you can't properly install it.
If it doesn't work then, try following these steps.
To add a new font
Note To reinstall standard Windows fonts, go to the "To reinstall the standard fonts included with Windows" section.
To install a font, follow these steps:
Click Start, and then click Run.
Type the following command, and then click OK:
%windir%\fonts
On the File menu, click Install New Font.
In the Drives box, click the drive that contains the font that you want to add.
Note The floppy disk drive is typically drive A or drive B. The CD drive is typically drive D.
In the Folders box, click the folder that contains the font that you want to add, and then click OK.
In the List of fonts box, click the font that you want to add. To select more than one font at a time, press and hold the CTRL key while you select each font.
Click to select the Copy Fonts To Fonts Folder check box. The new font is saved in the Windows\Fonts folder.
Click OK.
From the Microsoft knowledge base
If all else fails, you'll have to download the font again to ensure you have a proper/uncorrupted version.
