Installation of files:
Includes integrated support for "deflate", bzip2, and 7-Zip LZMA file compression. The installer has the ability to compare file version info, replace in-use files, use shared file counting, register DLL/OCX's and type libraries, and install fonts.

FontInstall
Description:
Tells Setup the file is a font that needs to be installed. The value of this parameter is the name of the font as stored in the registry or WIN.INI. This must be exactly the same name as you see when you double-click the font file in Explorer. Note that Setup will automatically append " (TrueType)" to the end of the name.
If the file is not a TrueType font, you must specify the flag fontisnttruetype in the Flags parameter.

It's recommended that you use the flags onlyifdoesntexist and uninsneveruninstall when installing fonts to the {fonts} directory.
To successfully install a font on Windows 2000/XP, the user must be a member of the Power Users or Administrators groups. On Windows NT 4.0 and earlier, anyone can install a font.
Example:
Source: "OZHANDIN.TTF"; DestDir: "{fonts}"; FontInstall: "Oz Handicraft BT"; Flags: onlyifdoesntexist uninsneveruninstall
