如何克服 Docker Desktop 3.3.3 的安装失败“对象引用未设置为对象的实例”？

Question

I have been trying to update the version of Docker Desktop on my laptop. The latest version as of a couple of weeks ago is Docker Desktop 3.3.3. I downloaded the installer and double clicked on it to begin the installation. I confirmed execution, resulting in a window saying "Downloading package", with a heading of "Extracting installation manifest..." Then a window saying "Do you want to replace your current version of Docker Desktop 3.3.1 (63152) with this new one (64133)?" appears. After I click on "Yes", this attached error window pops up. I tried stopping and uninstalling the previous version (3.3.1), but my PC refuses to do this. I am at the end of my rope trying to get my PC to do the simplest installation. I have been working with Docker for just over a month and want to do some tutorials and labs so that I can hit the ground running once I have real work to do with it. I would appreciate any help I can get.

Had exactly the same problem as you. You have to delete the key "Docker Desktop" and all its sub-keys, situated at "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" in the Windows Key Registry.
