Windows 7 states that the font “Does not appear to be a valid font”.

This is an issue caused by how the Windows operating system handles font installation.

You will receive this error if you do not have system administrator privileges.

Please ensure that you have un-zipped the font files correctly and moved the font files onto a folder located on the computer before trying to install the fonts. You cannot install zipped or font files located on another drive or external location.

Also please ensure that you have only one version or format of the fonts installed. If you try to install a TrueType font when another version of the font is already installed you will receive this error.

There is also much information on the web that suggests this issue can also occur due to a system Firewall issue on the PC, specifically with Firewall settings. 

Please refer to your system administrator if you recieve this error.
