@GlennM I added an updated script.
You can use it like this: ./InstallChromeDriver.ps1 -OutputPath ./chromedriver.exe -Platform win32
On non Windows machines you'd not add an extension to the chromedriver:
./InstallChromeDriver.ps1 -OutputPath ./chromedriver -Platform mac-arm64

The problem with this script is that if the script exits early either having an error or if the chromedriver version is already installed, the ProgressPreference is never reset back to the old preference. Just have to make sure the reset is called before throwing any errors and exits.

@GeorgeSPS Good catch, any idea how to fix this?
I don't maintain this since I don't use it anymore.
