Chrome Beta is free to download, however there are certain things you must do in order to use it. First of all, Google requires you to be logged in to your Google account before you download the software. You will be asked for a Google login and password. This is done so you can sign in to your Google account if you ever lose your password. After that you are free to download Chrome Beta.
After you have downloaded the application you will need to install it. To do this you must either click on the "Preferences" link at the bottom right corner of the screen or click on the "About" tab at the top left corner of the screen. If you are not prompted to do so you need to run the Chrome Beta launcher. It will ask you to restart your computer. When you do this, your browser is ready to be used with Chrome Beta. After you restart your computer you should have new software installed. On your Windows machine go to the Chrome Beta application folder, which is in the same location as where you downloaded the software, and then open the Chrome Beta application by double clicking it.
In order to use Chrome, you will need to download the free trial and install it to your computer. After you have done this you can use your computer without having to pay anything. You can keep track of what you want to download on your free account. However, you will need to be signed into your Google account in order to download anything. For security reasons Google will not allow any non-Google accounts to be used to download the software.
