Install Chrome on Windows with a .bat file using PowerShell

Question

I was searching around and found a few hints but a few detail pieces are missing. Here is what I have:

install-chrome.bat

PowerShell -NoProfile -Command "&{Start-Process PowerShell -ArgumentList '-NoProfile -File install-chrome.ps1' -Verb RunAs}"

install-chrome.ps1

$client = New-Object System.Net.WebClient;
$client.DownloadFile("https://dl.google.com/chrome/install/ChromeStandaloneSetup64.exe", ".\ChromeStandaloneSetup64.exe");

.\ChromeStandaloneSetup64.exe /silent /install ;

Two things are not working as expected:

I still get a UAC popup even though the posts I found state that the above should start PowerShell in Admin mode.
I was expecting .\ would download the .exe to the directory the .ps1 and .bat scripts are located.

Any hints on how to solve this?

EDIT: Thanks to the reply from @TheIncorrigible1 I managed to solve the second part. Both options work more or less (it downloads it, but the installation throws an error locally) when I execute them directly in PowerShell:

< V3

$PSScriptRoot = Split-Path -Parent -Path $script:MyInvocation.MyCommand.Path
$uri = "https://dl.google.com/chrome/install/ChromeStandaloneSetup64.exe"
$path = "$PSScriptRoot\ChromeStandaloneSetup64.exe" 

$client = New-Object System.Net.WebClient
$client.DownloadFile($uri, $path)
& $path /install

V3+

$uri = "https://dl.google.com/chrome/install/ChromeStandaloneSetup64.exe"
$path = "$PSScriptRoot\ChromeStandaloneSetup64.exe" 
Invoke-WebRequest -Uri $uri -OutFile $path
& $path /install

But the batch still throws errors:

At line:1 char:62
+ ... tart-Process PowerShell -Verb RunAs -ArgumentList -NoProfile, -File,  ...
+                                                                 ~
Missing argument in parameter list.
At line:1 char:69

Missing argument in parameter list.
    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : MissingArgument

you can try to set __compat_layer variable in order to aoic the UAC - but it could not work. — npocmaka

Two things-

You don't need to wrap your batch command to powershell in a scriptblock and -ArgumentList expects an array of string arguments:

powershell.exe -NoProfile -Command "Start-Process -FilePath powershell.exe -ArgumentList @('-NoProfile', '-File', '%~dp0install-chrome.ps1') -Verb RunAs"

There's an automatic variable, $PSScriptRoot, to determine where your root directory is:

$uri = 'https://dl.google.com/chrome/install/ChromeStandaloneSetup64.exe'
if (-not $PSScriptRoot) {
    $PSScriptRoot = Split-Path -Parent -Path $script:MyInvocation.MyCommand.Definition
}
$outFile = "$PSScriptRoot\ChromeStandaloneSetup64.exe"

if ($PSVersionTable.PSVersion.Major -lt 3) {
    (New-Object -TypeName System.Net.WebClient).DownloadFile($uri, $outFile)
}
else {
    Invoke-WebRequest -Uri $uri -OutFile $outFile
}

& $outFile /silent /install

Any reason to use $client.DownloadFile($x,$y) instead of Invoke-WebRequest -Uri $x -Outffile $y?

Maximilian Burszley Over a year ago

@Paxz Nope, I was just copying the OP's code. They may be stuck on v2 (in which case my $PSScriptRoot suggestion needs more explanation).

Thannks for the reply, I am a bit confused regarding the -FilePath argument. And shouldn't there be another comma before -Verb. Lastly if I use the V3 version, how would I then execute the file?

Maximilian Burszley Over a year ago

@Thomas filepath is just explicitly calling out the argument you were passing implicitly. ArgumentList takes an array of strings so each of those is parsed as a string without the quotes. If you add another comma, you break the command.

I tried to execute this as you wrote it, but I always get an error (not sure how to post this here, so it is formatted right: At line:1 char:60 + Start-Process -FilePath PowerShell -ArgumentList -NoProfile, -File, ' ... + ~ Missing argument in parameter list. At line:1 char:67 + ... Process -FilePath PowerShell -ArgumentList -NoProfile, -File, 'C:\Pro ... + ~ Missing argument in parameter list.

Here you go:

$Path = $env:TEMP; $Installer = "chrome_installer.exe"; Invoke-WebRequest "http://dl.google.com/chrome/install/375.126/chrome_installer.exe" -OutFile $Path\$Installer; Start-Process -FilePath $Path\$Installer -Args "/silent /install" -Verb RunAs -Wait; Remove-Item $Path\$Installer
