On some installations of Windows 7, the following prompt may be displayed when running the Freetouch installer for the first time:
The Freetouch installer is digitally signed, but some installations of Windows 7 will require that Microsoft Windows KB3004394 (Support for urgent Trusted Root updates for Windows Root Certificate Program in Windows) be installed in order to verify the digital signature on the installer. The installer will install this update as part of the install process, but it is safe to proceed with the installation if you receive this message.
