The contents of the file social-lead-fox.exe cannot be extracted from the program.
You can download the application from its official website, because there is a version available for installation. I've downloaded that version and installed it on my PC and it worked normally. I've been using Windows 10 x64 bit as operating system where Social Lead Fox was installed.
Note: After installing you'll get a message that the development and software has been discontinued and another version needs to be used instead.
