Microsoft PowerPoint for Mac

Is there an available update to Office for Mac, but you just can’t install it because of the annoying INSTALL_VERIFICATION_FAILED_ALERT_info message? Well, it happens at times. However, it’s no reason for you to panic. After all, there are many ways to solve it.

What Is the INSTALL_VERIFICATION_FAILED_ALERT_info Error?

In some Office for Mac versions, the Microsoft Database Daemon and Sync Services play a vital role. Although they only work in the background, they still have to be closed to install any available updates. If you don’t disable them, there is a chance that you will encounter the Microsoft Office installation error INSTALL_VERIFICATION_FAILED_ALERT_info.

Now, if you encounter this error message, try the solutions we have suggested below:

Solution #1: Disconnect Your External Hard Disk Drive.

Are you currently using an external hard disk drive? If you are, try disconnecting it first. And then, install the update again. Sometimes, external peripherals that are connected to your Mac may interfere with the update installation; hence you can’t proceed.

If no external hard disk drive is connected to your Mac, proceed to the next solution.

Solution #2: Close All Active Applications.

To close all active applications on your Mac, simply follow these steps:

  1. Go to the Apple menu.
  2. Select Force Quit.
  3. The Force Quit Applications window should now open. Click on the application you want to close.
  4. Choose Force Quit.
  5. Repeat steps 1 to 4 until all active applications are closed.

Take note that if an application is forced to quit, all unsaved changes will be lost.

Solution #3: Double-Check If the Update Has Already Been Installed.

If you are seeing the INSTALL_VERIFICATION_FAILED_ALERT_info error message, it could mean that the update has already been installed. Therefore, you need not install it again.

To verify that you are not installing the same update, follow the instructions below:

  1. Open any Office for Mac application. For example, you can launch Microsoft Word.
  2. Go to the Word menu.
  3. Select About Word. Take note of the software version. It should be displayed under the application’s name.
  4. Close the About Word window.
  5. Navigate to the Help menu.
  6. Choose Check for Updates.
  7. Press Check for Updates again.
  8. Take note of the update version.
  9. If the version of the software that was displayed in the About Word window is less than the update version, then it is safe to install the update. Otherwise, you need not do anything.

Solution #4: Check If Microsoft Is Listed Under Applications.

If you don’t see the Microsoft Office folder under Applications, then it is possible that Microsoft Auto Update cannot detect Microsoft Office on your Mac. This is why you are seeing the INSTALL_VERIFICATION_FAILED_ALERT_info error and cannot proceed with installing updates.

To make sure that the Microsoft Office folder is in the right location, here’s what you should do:

  1. Open the Go menu.
  2. Select Applications.
  3. Check if the Microsoft Office folder exists.

If you don’t see it there, you need to find it and move it to Applications. Here’s how you do it:

  1. Close all active and running applications.
  2. Go to the File menu.
  3. Select Find.
  4. Make sure the search parameters are set to Any and Kind.
  5. In the search field, input Office 2008 or Office 2011.
  6. Hit Enter.
  7. Find the folder in the search results. Drag it to your Desktop.
  8. Navigate to the Go menu.
  9. Choose Applications.
  10. Drag the folder from your Desktop to Applications.

Solution #5: Check If You Are Using the Correct Language Settings.

It is important that the language of the update file you downloaded matches the current installation language of your Office for Mac. To verify that your language settings are correct, follow these steps:

  1. Go to the official page of Microsoft for Mac.
  2. At the topmost portion of your screen, check the country setting if it matches the language of the Office for Mac that is currently installed.
  3. Navigate to Downloads.
  4. Open Office for Mac Updates.
  5. Go to Available Downloads and select the update version of the product you want.
  6. Hit Download Now.
