If your network is blocking you (or for any other reason) from performing a one-click update, you can manually obtain the update.
Enter into an account and click the Help tab.
Then, click on the bottom half of the Software icon > and click on Manual Update.
This will display the Manual Update window below.
1. Click the link to download the update. If your network policies are blocking you (and perhaps the reason the one-click failed), have your IT department download the file for you and then copy it to your computer.
2. Point to the location of the downloaded file.
3. Click Update Service Pack to install.
Afterwards, you can verify the build you are on by clicking on Help > About.
