Anaconda no se instala completamente en Windows 7

Question

[editar] El problema aquí resultó ser un problema con mi disco duro.

Estoy intentando instalar Anaconda3 en Windows 7. No tengo otras instalaciones de Python. Lo he intentado varias docenas de veces, limpiando y reiniciando entre cada ejecución. Probé varias versiones del instalador de Anaconda3. He probado todas las combinaciones de administrador/no administrador y RUTA/registro. No importa lo que intento, obtengo el mismo resultado: la instalación se completa y los paquetes se extraen, pero no tengo accesos directos al menú y no puedo ejecutar nada. Mostrar detalles tiene un montón de errores que se refieren a módulos faltantes y la imposibilidad de ejecutar conda.exe. Pude instalarlo sin problemas en una caja diferente con Windows 10.

Salida parcial pegada a continuación, comenzando con el primer error que aparece después de la pila de mensajes de extracción.

Answer 1

Antes que nada pido disculpas por mi pregunta disfrazada de respuesta. Botón equivocado.
Mi solución es:

1. Desinstale todas las versiones de Anaconda
2. Busque c:\users\user_name\appdatael directorio conda y elimínelo.
3. Busque c:\users\user_name\el directorio .conday elimínelo.
4. instalarAnaconda3-2019.03-Windows-x86_64.exe 661.7M 2019-04-04 16:00:30 bfb4da8555ef5b1baa064ef3f0c7b582
5. Ejecutarconda update conda
6. Ejecutarconda update anaconda
7. Ejecutarconda update --all
8. Ejecutarconda list anaconda$

El número 8 muestra la versión real.
Espero que esto ayude a alguien más.
