Cannot uninstall Docker for Windows

Docker Desktop
21

Same problem here. When trying to install the latest community edition exe installer it thinks an older version still exists and prompts with “Do you want to replace your current version of Docker for Windows with this new one 17.09.0-ce-win33 (13620)?”. When I hit “yes” the main dialog simply says “Installation canceled”.

I tried all powershell scripts mentioned, tried manually blowing away anything to do with docker for windows on the file system as well as the registry, still same problem. Tried larshw’s link to remove a registry key but I didn’t have that key.

What registry key is this thing looking for??? I can’t figure it out. Installer log shows nothing of importance:
