Last updated: October 2026 · Tested on: Google Chrome 156.0.8078.74 (Official Build) (64-bit), Windows 11 (October 28, 2026)
To get the official Google Chrome offline installer, use Google’s standalone setup parameter (?standalone=1) or direct server link to download ChromeStandaloneSetup64.exe (164,567 KB) instead of the default 12.6 MB online stub that fails without internet.
Quick summary: This is for Windows 10 and Windows 11 users installing Chrome on PCs without internet access, behind strict firewalls, or across multiple machines. My verdict: use Google’s official standalone installer, not third-party repacks. One number to remember: the full 64-bit offline setup is 164,567 KB (~160.7 MB), compared to 12,973 KB (12.6 MB) for the standard online downloader.
Why the Standard Chrome Download Fails Offline (My File Size Test)
When you click the download button on Google’s default homepage, you do not get the full browser. Instead, Google delivers a small bootstrapper file named ChromeSetup.exe that requires an active internet connection to download the actual program files during setup.
On October 28, 2026, I downloaded both installers on Windows 11 to measure the real difference in your Downloads folder:
- Full Offline Installer (
ChromeStandaloneSetup64.exe): Weighed 164,567 KB (~160.7 MB). It is larger upfront, but it contains every file required to install Chrome completely offline. - Standard Online Stub (
ChromeSetup.exe): Weighed 12,973 KB (12.6 MB). It is faster to download initially, but it needs an active internet connection to finish.
Opening the Properties dialog for the standard ChromeSetup.exe file shows an exact size of 12.6 MB (13,283,768 bytes) and the description Google Installer (x86). Even on 64-bit systems, the online installer is a small 32-bit bootstrap file, not the browser itself.
If you use a firewall manager to restrict background data, this small installer may be blocked until you allow it. You can see how background updaters behave in my Malwarebytes Windows Firewall Control guide.

Google Chrome Offline Installer Options: 64-Bit, 32-Bit and MSI
Google provides different offline installers depending on your system and deployment needs. I tested only the 64-bit file, so the other sizes are marked as not tested.
| Installer Type | File Name | File Size | Installation Path | Best For |
|---|---|---|---|---|
| 64-Bit Standalone | ChromeStandaloneSetup64.exe | 164,567 KB (measured) | C:\Program Files with the all-users link, or the current user’s AppData with the standard link | Offline PCs & USB installs |
| 32-Bit Standalone | ChromeStandaloneSetup.exe | Not tested | Not tested | Legacy 32-bit Windows |
| Enterprise 64-Bit MSI | GoogleChromeStandaloneEnterprise64.msi | Not tested | System-wide (Group Policy) | IT admins & silent rollouts |
How to Download, Verify, and Install Chrome Offline
Follow these steps to make sure you download an authentic, unmodified 64-bit installer:
Step 1. Use the standalone parameter. Open Google’s standalone download URL. The ?standalone=1 parameter directs Google’s server to deliver the full 164,567 KB executable instead of the 12.6 MB stub. Adding system=true installs Chrome for all user accounts on the computer.
Step 2. Check the digital signature. Before you copy an installer to another PC, right-click it, select Properties, and open the Digital Signatures tab. The signer should be Google LLC with the sha256 digest algorithm. In my test, I checked the installer I downloaded from Google (ChromeSetup.exe) and saw exactly that. Do the same on the standalone file before you share it.
Download source matters. In my Softonic WinRAR download test, the portal offered an older version than the developer’s official site.
Step 3. Run the installer offline. Copy the executable to your target PC via USB and double-click it. The whole browser package is inside the ~160.7 MB file, so setup doesn’t need to download anything. When Chrome launches, click Stay signed out if you prefer to use the browser locally without linking a Google account.
Step 4. Confirm the 64-bit build. Navigate to chrome://settings/help. In my test, Chrome confirmed Version 156.0.8078.74 (Official Build) (64-bit), with the active tab using only 64.9 MB of memory.
Why Unofficial “Chrome Portable RePacks” Are Risky
Many download portals distribute unofficial “Chrome Portable RePacks” hosted on file-sharing sites. I would avoid them for three reasons:
- Broken updates: A repack can remove or alter Google’s update service, so Chrome may fail to update properly.
- Hard to verify: A modified file won’t give you a trustworthy Google LLC result in the Digital Signatures check from Step 2.
- Security risks: Running modified browser executables from unverified sites risks exposing your saved passwords and session cookies. Before using third-party links, review the safety checks in how to check any link before you click. If you have already run an unverified repack, scan your system using the utility covered in my Microsoft Safety Scanner review.
To keep your Chrome data on a USB drive without a repack, install the official standalone setup, then launch Chrome with a shortcut that uses the --user-data-dir="E:\ChromeProfile" command-line argument. Chrome still runs from your PC, and only your profile data lives on the drive.
Who Should Skip the Offline Installer
Skip the 164,567 KB standalone installer if you are installing Chrome on a single computer with a reliable, high-speed connection. In that case, the standard 12.6 MB stub completes setup quickly without leaving a 160 MB installer on your drive.

Final Verdict
Use Google’s official standalone installer (ChromeStandaloneSetup64.exe) if you need a reliable offline install across multiple PCs without download failures. Skip it if you are setting up a single laptop with fast Wi-Fi, where the standard 12.6 MB installer works fine. One concrete reason: the official 160.7 MB package is complete, so you download it once and keep away from the update problems and security risks of unofficial repacks.
