When using WOW64, C:\Windows\System32 actually points to C:\Windows\SysWow64.

Hi iankingori, the context is in the referenced issue: #393.

Namely, the docker-ce helper script in this repository installs docker.exe by copying it directly to C:\Windows\System32. When you're running a 32 bit application (e.g. msbuild.exe for Visual Studio 2019 or older), the %windir%\System32 directory is mapped to %windir%\SysWOW64 and therefore any attempts to call docker.exe installed by this helper script by a 32-bit application will fail, because it doesn't exist in the path.

TL;DR: this PR makes docker.exe available for 32 bit applications.
