There is a version of FaxLauncher Pro released in 2011 that is said to be compatible with Windows 7. There is a chance to run it in Windows 7, but that possibility is ruled out because the download on the official website is not working as well which makes testing impossible.
The only option right now is to get in touch with developers to ask them about the status of the FaxLauncher Pro. They have a page with the necessary options to reach them.
