Não é possível desinstalar o python 3.5 no Windows

Question

Estou tentando desinstalar a versão Python do Windows 64 bits no meu laptop Win7, mas não consigo fazê-lo.

Ele detecta uma versão instalada para fornecer a opção de modificar, reparar ou desinstalar. Mas ao inicializar a desinstalação, ele diz "Nenhuma instalação do Python 3.5 foi detectada".

Eu tentei fazer um reparo e, em seguida, desinstalar, mas sem sucesso. Eu também tentei várias soluções mencionadas online, mas nada funciona.

A seguir está o log:

Answer 1

A solução que funcionava era clicar em reparar do instalador e deixá-lo falhar. Depois que ele falhou, eu desinstalei e reinstalei e funcionou bem.

Todos os passos feitos através do instalador padrão.
