Office installations include a built-in repair tool, and that’s the first place to turn when things go awry. The absolute worst case requires running a cleanup tool on the current Office installation, followed by a clean install of a new copy of Office. That has never failed in my experience, any time I’ve had to go that far. The steps to access the repair tool vary depending on your operating system.

Recover data when you can't open the workbook in Excel

This sort of thing does occur from time to time, and it is often quite easy to repair. If one or more Office apps is acting glitchy, work your way through this series of repair maneuvers, starting with the simplest. Come with me as I write this article in real time as I try to resolve the issue. If you’re lucky, you’ll find your problem covered, and SaRA will fix it for you. However, let’s return to Step 1 to start this process where it also usually ends. You’re working on a document or a spreadsheet, or using email, and BAM!

If you’re not sure, the Installed Apps list we started with is a good place to look. If you’re coming from section 2, grab the download link for what Microsoft calls the "uninstall support tool" in its Support pages. Its filename is SetupProd_Offscrub.exe, so I’ve gotten in the habit of calling it "OffScrub" myself.

Beyond Tools: Why a SAM Tool Isn’t a Complete Solution

In my experience, only 1 in 10 Office installations will still fail to work. If yours works, count yourself lucky and get back to your normal routine. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. If a Microsoft 365 application such as Word or Excel isn't working correctly, sometimes restarting it will fix the problem. If that doesn't work, you can try repairing it.

Want more options?

Just before the progress bar completed, a notification popped up to tell me that my Office install was complete. The installer window changed to an animated display that included what’s shown in Figure 8. The easiest way to determine this is to take the document to a different computer running another copy of Microsoft Office and attempt to open the document there. If it works, then it’s likely that your installation of Office is the problem, not the document. If it fails, it’s likely the document itself is at fault. Below the reset section in the Office Advanced Options (shown above) is an uninstall link.

• The error indicates that my previous open was unsuccessful, and asks if I would like to open Excel in safe mode.
• If yours works, count yourself lucky and get back to your normal routine.
• When the process completes, the "Done repairing" window appears, as shown in Figure 6.
• The absolute worst case requires running a cleanup tool on the current Office installation, followed by a clean install of a new copy of Office.
• If it works, then it’s likely that your installation of Office is the problem, not the document.
• If the steps above don’t help, the next step is to uninstall and reinstall Office.
• You can also take some preventive measures to avoid losing your work by automatically saving a backup copy of your workbook or creating a recovery file from time to time.

Start in Settings

Even on my 2012 vintage test machine, it was done in under a minute (on a healthy Office installation, I cheerfully confess). When the process Common Outlook errors explained completes, the "Done repairing" window appears, as shown in Figure 6. Once you’ve clicked Change, you may see a User Account Control window asking for permission to run the repair program. Click Yes, and the built-in Office repair window appears. The Quick Repair option, as shown in Figure 2, is selected by default.

Repair an Office application

You’ll then need to re-download and reinstall Microsoft Office. When complete, a checkmark appears next to the Rest button. Unzip to a folder of your choosing, then run the file named SaraSetup.exe to install the program.

When you're done, you might need to restart your computer. I want comments to be valuable for everyone, including those who come later and take the time to read. Microsoft SaRA is the Microsoft Support and Recovery Assistant. If you’re lucky, when you open your formerly balky or misbehaving Windows app, all will be well. With the Quick Repair radio button selected, click the Repair button near the bottom right corner of the window. Please relax, and don’t give in to panic or upset.

At least two computers at my workplace don't have Office (or its components) showing in the Installed Apps. After the list of installed apps populates (it can take some time, depending on how much you have installed), scroll down and look for Microsoft 365 (Office). Then it took another 4 minutes and 24 seconds for the (genuine) progress bar shown above to download all the files. Watching my network access while this was underway, I saw the typical on-again, off-again download behavior for Windows Update occurring here. The download meter ran as high as 180 Mbps, and as low as a few Kbps while the download was underway. Office’s Online Repair option works and goes through exactly the same steps as Quick Repair, so I won’t walk through all those screen shots again.

You’ll see a dialog box like the one shown in Figure 9 open up and ask you to confirm installation. If you have any Office applications open, you’ll be asked to close them before the repairs can complete. On my test machine, for example, I had Outlook open. This provoked the request shown in Figure 4 (where, of course, I clicked Continue to close Outlook so repairs could work through to completion). A window opens to ask you if you’re ready to commence repairs.
