How to install fonts on Windows - FontPlanet
Most typefaces are downloaded as an extractable zip file. Your system should know how to handle these, but if not you can usually use a program like WinZip to open them.
WINDOWS INSTALATION
Unzip the folder containing the fonts first. Fonts cannot be installed if they are zipped.
Right click on the font file and select Install.
Alternately, you can manually install fonts this way:
Search for Fonts in the search box by the start menu.
Click on the Fonts (Control Panel) link to open the Fonts Manager
Drag and Drop or Copy and Paste the unzipped fonts into the Fonts Manager to install.
