How Do I Install Fonts in Photoshop?
Using Adobe Photoshop, you can add text to any image composition you're working on. Without a good set of fonts, however, the text may end up a little less visually dynamic than you'd like. Photoshop doesn't have its own font installation process, which is one less process to learn. Instead, adding a new font to Photoshop only requires that you install the new font onto your computer: Photoshop uses all of the fonts you already have.
Installing fonts on Windows 7 and Windows 8.1 works the same way: Locate the font file on your computer, right-click it and select "Install" from the menu. Once the font has been installed, the font is ready to use in Photoshop. If Photoshop is open while installing the font, you may have to close and re-launch Photoshop in order to use the new font.
Handling Documents with Text Layers
So long as your computer already has the font installed, opening a document with text layers poses no problem and all layers should load correctly. However, if the document's text layers use a font not installed on your computer, Photoshop informs you with a pop-up message and prompts you to select a new font. In order to display the original font, close the file without saving it, then download and install the font onto the computer before reopening the Photoshop document.
