No se puede instalar GitHub en Windows 7 (64 bit)

El error actual que recibo: la validation de la aplicación no tuvo éxito. No se puede continuar

Detalles del problema: tenía instalado GitHub en Windows, pero creé una count nueva (pagada) que decidí usar en curso. He tenido GitHub ya instalado en Windows y he iniciado session con la count anterior.

Ayer, salí de la count anterior porque quería iniciar session en la nueva count. Luego, después de cerrar la session, la aplicación solicitó que haya una versión más nueva disponible para download, así que hice clic en ella para actualizar la aplicación. Se produjo un problema durante la actualización, así que desinstalé la aplicación y reinstalé la versión más nueva desde este enlace: https://windows.github.com/

Básicamente, la aplicación comenzará a instalar desde serveres Amazing y cuando se descarga me aparece este error: la validation de la aplicación no tuvo éxito. No se puede continuar

Traté de eliminar el contenido de la carpeta "2.0" sin suerte. También me aseguré de proporcionar una regla de exception para la aplicación de installation dentro de mi Firewall, pero eso no ayudó. También intenté reinstalar .Net Framework 4.5 sin suerte.


Esto es lo que obtengo cuando hago clic en el button "Detalles":
