Common installation errors with Microsoft Office and how to avoid them

If you’ve just purchased an Office 365 subscription, or the retail or download version of Office 2019, installing on your PC should be as easy as running the executable file and patiently waiting.

Sometimes, though, you might be faced with an error code, or something else could go seriously wrong during the install process. In this guide, we’ll take a look at some common installation errors in Office, and how you can avoid them.

Office takes too long to install, or error codes 2002-4, 12007-4, or 12152-4

When you download Office from Microsoft or another online retailer, the installer will need to connect to the internet to grab the install files. Sometimes, it might take too long to install, and that could be due to a slow connection.

If that’s the case, you might want to cancel the install and restart your computer. You also might want to try and temporarily disable your Antivirus software and your firewall during install.

On the restart, you might see that the Office installation has completed, despite what the progress indication on the installer might say. If not, you can try installing again.

If all else fails, you can download an offline installer for Office. Specific instructions on how to do so are available through Microsoft. Getting the installer involves visiting Office.com and signing in with your account, choosing Install Office, and selecting Other Options from the download and install window.

If the Office installer hangs at 90%, this could be due to your system being busy. According to Microsoft, a prime cause of this is Windows Update, and Windows using the Update Installer in the background while Office is installing.

  • Press ctrl+alt+delete on the keyboard (hold down all keys simultaneously), and select Task Manager (or Start Task Manager on Windows 7
