How do I downgrade my Google Chrome version?

Downgrading Google Chrome can be achieved using the command line interface and the Chrome Standalone Enterprise MSI installer. Here's how:

Steps to Downgrade Google Chrome

The process involves using the msiexec command in the command prompt.

You'll need to use one of the following commands, depending on your situation:

Scenario 1: If you want to downgrade to the version you last manually installed using the MSI file, use:
```
msiexec /fvomus GoogleChromeStandaloneEnterprise.msi ALLOWDOWNGRADE=1
```
Scenario 2: Otherwise, if you don't remember the version or haven't manually installed with MSI before, use:
```
msiexec /i GoogleChromeStandaloneEnterprise.msi ALLOWDOWNGRADE=1
```

Let's break down what each part of the command does:

msiexec: This is the command-line tool for installing Windows Installer packages (MSI files).
/fvomus: This switch forces a reinstall, overwriting existing files, verifying the MSI, and re-caching the installer. It's used when you know you're downgrading to a specific MSI you used before.
/i: This switch tells msiexec to install or configure a product.
GoogleChromeStandaloneEnterprise.msi: This is the name of the MSI file. Important: Make sure this file is in the directory where you are running the command from, or specify the full path to the file.
ALLOWDOWNGRADE=1: This crucial parameter allows the downgrade to proceed. Without this, the installer will likely refuse to install an older version.

Obtain the MSI File: You need to download the specific older version of the GoogleChromeStandaloneEnterprise.msi file that you want to downgrade to. Be sure to get it from a trusted source.
Run as Administrator: You'll need to open the Command Prompt as an administrator to execute these commands.
Data Loss: Downgrading can sometimes cause issues with your Chrome profile or data. Back up your important data (bookmarks, passwords, etc.) before proceeding.
Automatic Updates: Chrome will likely try to update itself again automatically. You may need to configure Chrome's update settings (or use group policies if you're in an enterprise environment) to prevent this.
