O Anaconda não consegue instalar totalmente no WIndows 7

Question

[editar] O problema aqui acabou sendo um problema com meu disco rígido.

Estou tentando instalar o Anaconda3 no Windows 7. Não tenho outras instalações do Python. Eu tentei várias dezenas de vezes, limpando e reiniciando entre cada execução. Eu tentei várias versões do instalador Anaconda3. Eu tentei todas as combinações de admin/not admin e PATH/register. Não importa o que eu tente, obtenho o mesmo resultado: a instalação é concluída e os pacotes são extraídos, mas não tenho atalhos de menu e não consigo executar nada. Mostrar detalhes tem vários erros referentes a módulos ausentes e à incapacidade de executar conda.exe. Consegui instalar sem problemas em uma caixa diferente executando o Windows 10.

Saída parcial colada abaixo, começando com o primeiro erro que aparece após a pilha de mensagens Extrair.

Answer 1

Em primeiro lugar peço desculpas pela minha pergunta disfarçada de resposta. Botão errado.
Minha solução é:

1. Desinstale todas as versões do Anaconda
2. Verifique c:\users\user_name\appdatao diretório conda e exclua-o
3. Verifique c:\users\user_name\o diretório .condae exclua-o
4. instalarAnaconda3-2019.03-Windows-x86_64.exe 661.7M 2019-04-04 16:00:30 bfb4da8555ef5b1baa064ef3f0c7b582
5. Executarconda update conda
6. Executarconda update anaconda
7. Executarconda update --all
8. Executarconda list anaconda$

O número 8 mostra a versão real.
Espero que isto ajude alguém.
