Last Docker Desktop for Windows installation crash

Question

I am trying to install the last version of Docker for Windows from this link https://docs.docker.com/docker-for-windows/install/

The installation always crash with the following error:

Unable to check availability for Windows feature Hyper-V: Le fichier spécifié est introuvable.

à Docker.Core.Pipe.NamedPipeClient.Send(String action, Object[] parameters) dans C:\workspaces\stable-18.09.x\src\github.com\docker\pinata\win\src\Docker.Core\pipe\NamedPipeClient.cs:ligne 36 à Docker.Actions.DoStart(SynchronizationContext syncCtx, Boolean showWelcomeWindow, Boolean executeAfterStartCleanup) dans C:\workspaces\stable-18.09.x\src\github.com\docker\pinata\win\src\Docker.Windows\Actions.cs:ligne 92 à Docker.Actions.<>c__DisplayClass21_0.b__0() dans C:\workspaces\stable-18.09.x\src\github.com\docker\pinata\win\src\Docker.Windows\Actions.cs:ligne 155 à Docker.WPF.TaskQueue.<>c__DisplayClass19_0.<.ctor>b__1() dans C:\workspaces\stable-18.09.x\src\github.com\docker\pinata\win\src\Docker.WPF\TaskQueue.cs:ligne 59

This might be because I don't have Hyper V on my computer but It should allow me to install it with Docker Desktop for Windows. My operating system is Windows 10 Pro 64 bits.

Answer 1

I had to manually activate Hyper-V. In order to do that I had to:

1. Resolve Windows update issues with Microsoft wu10.diagcab tool, launched in administrator mode
2. Activate Hyper-V with the following command, in a Powershell launched in administrator mode: Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All
