Install Office 2008 Trial Version

To test the trial version of Office for Mac 2008, you can download the trial and test out Office 2008 for 30 days free. Microsoft only offers the Office 2011 trial at this time.

Click on Download Test Trial. I advise reading the FAQs first.

After you enter your name and contact info, you will be presented with this screen.

Click on the Download Now link. You can copy your Product Key to paste during the install. Everything in this screen will be sent to you in the welcome email. You only need the Product Key to continue with the install. The email will contain your order number and your password along with your Product Key. SAVE THIS EMAIL!

By default, the installer will be downloaded to the Downloads folder. You can click on the find icon to locate.

Launch the installer. You must be an admin user to install.

It's best to quit all running applications before installing. Easy way: Select Log out of your User under the Apple in the menu bar. When you Log in, hold down the Shift key. This will disable all login items.

Do NOT remove old versions of Office at this time. You can always go back later and remove using "Remove Office" found in Additional Tools folder.

Enter your info in the Setup Assistant. When it completes you are given two options. Registration is not required. All it does is add you to a mailing list. This is NOT the activation for your product.

Almost immediately, the Microsoft AutoUpdater will launch.

You'll see it in the Dock. Select Keep in Dock.

Before you download and install the latest updater restart your computer for best results. See Restarting your computer after an update is important!

Remember to log in with Shift key down to disable all start up items. Select the MAU from the Dock and download the 12.2.1 updater. (note in the future, the version info here could change)


After updating, restart again. This time log in normally. Verify you are updated.

The true test of any update is the Microsoft Component Plugin. You'll note the Microsoft Component Plugin is v 12.2.1, but the applications are 12.2.0. More info: Verify your update.

When you launch any Office application, you will see this screen. Click on Try to test Office for free for 30 days. If you decide to purchase the trial version, click on Buy Now. You will receive an Activation code that you can enter in the Activate Purchase box.


If you decide not to purchase the trial version or want to install a retail version of Office 2008, you will need to fully remove all traces of the Office 2008 Trial version.

  1. Run "Remove Office" found in this location: Applications/Microsoft Office 2008/Additional Tools/Remove Office/
