If you need to install the downloaded Founder font, you can use the following method:
Copy the Founder font file to be added to the "Fonts" folder under "Control Panel".
After copying is completed, double-click the font file to run, and the system will automatically detect and start installing the font.
After the installation is completed, the system will automatically enable the font and the font can be used.
Note: If you cannot find the "Fonts" folder, you can use the C:\Windows\Fonts folder directly instead.
