Download Older Version of Google Chrome using Powershell

Google doesn’t provide links to the older versions of Chrome, once the new versions are released, so you need to either have a copy of the installers or browse around looking for legitimate links.


You can get links to the older version of Chrome using Google Update API. Using this method, you can go around 11 versions back (1 year).

Powershell code for Windows 64-bit (change chrome version to number to the desired version).


$ChromeVersion = '115'
$requestId = ([String][Guid]::NewGuid()).ToUpper()
$sessionId = ([String][Guid]::NewGuid()).ToUpper()
$xml = @"
<?xml version="1.0" encoding="UTF-8"?>
<request protocol="3.0" updater="Omaha" updaterversion="" shell_version=""
    ismachine="1" sessionid="{$sessionId}"
    installsource="update3web-ondemand" requestid="{$requestId}"
    dedup="cr" domainjoined="0">
    <hw physmemory="4" sse="1" sse2="1" sse3="1" ssse3="1" sse41="1" sse42="1" avx="1" />
    <os platform="win" version="10.0" sp="" arch="x64" />
    <app appid="{8A69D345-D564-463C-AFF1-A69D9E530F96}" version="5.0.375" nextversion=""
        ap="x64-stable-statsdef_0" lang="" brand="GCEB" client="" installage="0">
        <updatecheck targetversionprefix="$ChromeVersion"/>

$webRequest = @{
    Method    = 'Post'
    Uri       = ''
    Headers   = @{
        'Content-Type' = 'application/x-www-form-urlencoded'
        'X-Goog-Update-Interactivity' = 'fg'
    Body      = $Xml
$result = Invoke-WebRequest @webRequest -UseBasicParsing
$contentXml = [xml]$result.Content
$status = $
if ($status -eq 'ok') {
    $package = $
    $urls = $ | ForEach-Object { $_.codebase + $ }
    Write-Output "--- Chrome Windows 64-bit found. Hash=$($package.hash) Hash_sha256=$($package.hash_sha256)). ---"
    Write-Output $urls
else {
    Write-Output "Chrome not found (status: $status)"

Powershell script to discover links for Mac and Windows 32-bit is here.

How it works

I captured the Chrome conversation with the update server using Fiddler.

The browser asks server for the latest version of Chrome.
