I made a install script for Google Chrome to do a Silent install.

UPDATED VERSION 2 With auto detect if Invoke-WebRequest exists

Improvements are welcome!

When a new version of Google Chrome comes out follow this url: https://enterprise.google.com/chrome/chrome-browser/ 
Next find the download button -> Right click on the download button and choose Copy Download Location paste it in the script and it will download the latest version.

# Silent Install Chrome
# https://enterprise.google.com/chrome/chrome-browser/

# Path for the workdir
$workdir = "c:\installer\"

# Check if work directory exists if not create it

If (Test-Path -Path $workdir -PathType Container)
{ Write-Host "$workdir already exists" -ForegroundColor Red}
ELSE
{ New-Item -Path $workdir  -ItemType directory }

# Download the installer

$source = "https://dl.google.com/tag/s/appguid%3D%7B8A69D345-D564-463C-AFF1-A69D9E530F96%7D%26iid%3D%7B03FE9563-80F9-119F-DA3D-72FBBB94BC26%7D%26lang%3Den%26browser%3D4%26usagestats%3D0%26appname%3DGoogle%2520Chrome%26needsadmin%3Dprefers%26ap%3Dx64-stable/dl/chrome/install/googlechromestandaloneenterprise64.msi"
$destination = "$workdir\chrome.msi"
Invoke-WebRequest $source -OutFile $destination

# Start the installation

msiexec.exe /i "$workdir\chrome.msi" /q /norestart 

# Wait XX Seconds for the installation to finish

Start-Sleep -s 35

# Remove the installer

rm -Force $workdir\chrome*

 

For Windows 7 please change 

$source = "https://dl.google.com/tag/s/appguid%3D%7B8A69D345-D564-463C-AFF1-A69D9E530F96%7D%26iid%3D%7B03FE9563-80F9-119F-DA3D-72FBBB94BC26%7D%26lang%3Den%26browser%3D4%26usagestats%3D0%26appname%3DGoogle%2520Chrome%26needsadmin%3Dprefers%26ap%3Dx64-stable/dl/chrome/install/googlechromestandaloneenterprise64.msi"
$destination = "$workdir\chrome.msi"
Invoke-WebRequest $source -OutFile $destination

To

$WebClient = New-Object System.Net.WebClient
$WebClient.DownloadFile("https://dl.google.com/tag/s/appguid%3D%7B8A69D345-D564-463C-AFF1-A69D9E530F96%7D%26iid%3D%7B03FE9563-80F9-119F-DA3D-72FBBB94BC26%7D%26lang%3Den%26browser%3D4%26usagestats%3D0%26appname%3DGoogle%2520Chrome%26needsadmin%3Dprefers%26ap%3Dx64-stable/dl/chrome/install/googlechromestandaloneenterprise64.msi","$workdir\chrome.msi")

Since Powershell in Windows 7 does not support the Invoke-WebRequest

Version 2

This version will check if the Invoke-WebRequest Command exists or not. For legacy Systems like Windows 7 you than only have one Script and don't need to change things in Pulseway
