Why Won't Microsoft Office Install


Existing Office 2016 for Mac customers will be seamlessly upgraded to 64-bit versions of Word, Excel, PowerPoint, Outlook, and OneNote as part of the August product release (version 15.25). This affects customers of all license types: Retail, Office 365 Consumer, Office 365 Commercial, and Volume License installations.

Deployment options for the 64-bit update

AutoUpdate (MAU)

Customers who use Microsoft AutoUpdate (MAU) to keep their Office applications up-to-date will see a 'regular' monthly update notification when their selected channel is upgraded to 64-bit builds. Depending on which version is installed on the local computer, MAU will offer either a delta or full update. The update package size does not change between 32-bit and 64-bit versions. Also, MAU can deliver a delta update when applicable to update a user from 32-bit to 64-bit applications. Therefore, customers won't experience a sharp increase in download activity. For the release to the Production channel, customers will see '(64-bit)' in the update title to make them aware that this is a 64-bit update.

For information about how to use the MAU, see Check for Office for Mac updates automatically.

Manual updates

The August release of Office for Mac is available for manual download. The following file provides a 64-bit package to replace existing 32-bit applications with 64-bit variants during installation:

Virus-scan claim

Microsoft scanned this file for viruses, using the most current virus-detection software that was available on the date that the file was posted. The file is stored on security-enhanced servers that help prevent any unauthorized changes to it.

Volume License Service Center

Volume License customers typically get their Office 2016 software from the Volume License Service Center (VLSC). These builds are refreshed infrequently and are typically aligned with new language editions. The VLSC will continue to offer 32-bit installers (15.23) until November 2016. However, all updater packages that are released after August will be based on 64-bit builds. Therefore, a VLSC customer who updates either manually or through AutoUpdate will be transitioned to 64-bit builds.

64-bit only

The Mac operating system has been 64-bit for several years. Unlike for Windows, there's no choice between running a 32-bit or 64-bit version of the Mac operating system. Similarly, we won't offer a choice between 32-bit and 64-bit versions of Office 2016 for Mac. After each 'channel' is transitioned per the rollout schedule, only 64-bit builds will be available.

Effect on third-party applications and add-ins

The transition to 64-bit Office for Mac was announced in April 2016. IT Pros will want to understand which compiled add-ins are deployed to the users whom they manage so that they can assess the effect of the upgrade. The following Microsoft Office website summarizes the issues that affect the more common add-ins that are used together with Office 2016 for Mac:

Tools for inspecting product architecture

To verify the architecture of an Office application (that is, to understand whether you have a 32-bit or 64-bit build), start the application, open the Activity Monitor, and then enable the Kind column.

You can also use the file command in a terminal session to inspect the binary. For this use, type file -N <path of binary>.This method can be used with for any binary file, including third-party add-ins.

The file command returns one of three values.

Return valueMeaning
Mach-O 64-bit executable x86_6464-bit binary
Mach-O executable i38632-bit binary
Mach-O 64-bit executable x86_64FAT binary (compatible with both 32-bit and 64-bit processes)
Mach-O executable i386FAT binary (compatible with both 32-bit and 64-bit processes)

Options for reverting to 32-bit installations

There may be situations in which the customer has to change code that's not 64-bit ready. If customers can't immediately move forward to 64-bit builds, we will make available a one-time 32-bit update for the 15.25 release in addition to the default 64-bit updates. The 32-bit updates will be available only for manual download from the Office CDN.

The latest 32-bit release of Office 2016 for Mac (15.25.160818) can be downloaded from

Customers who manually install the 32-bit release won't be offered the 64-bit version of 15.25 through MAU. However, MAU will offer the 64-bit version of 15.26 in September 2016. Therefore, customers have a limited time to remain on 32-bit builds.

If a customer has already upgraded to the 64-bit update of Office for Mac 15.25 and wants to revert to the 32-bit version, follow these steps:

  1. Exit all open Office 2016 applications.
  2. Start Safari, and then browse to to start the download of the 32-bit installer.
  3. Double-click the downloaded package, and then follow the instructions.

The 64-bit installation has a build date of 160817. The 32-bit version has a build date of 160818.



When you try to open a file in any Microsoft Office program that’s listed in the 'Applies to' section, you receive one of the following error messages:

Filename is not valid.

Microsoft Office Won't Download On Mac Laptop

The file could not be accessed.

The path you entered, 'filename', is too long. Enter a shorter path.

filename could not be found. Check the spelling of the filename, and verify that the file location is correct.

A DDE error has occurred, and a description of the error cannot be displayed because it is too long. If the filename or path is long, try renaming the file or copying it to a different folder.


This issue occurs when you open a file from a mapped drive, a UNC path, or a URL (web address).


This issue occurs because of a character limit on creating and saving files in Office products. This issue occurs if the path of the file that you open or save meets the following condition:

  • Microsoft Word, Microsoft PowerPoint, and Microsoft Access: The total length of the path and the file name, including file name extension, exceeds 259 characters.

  • Microsoft Excel: The total length of the path and the file name, including file name extension, exceeds 218 characters.


This limit includes the three characters that represent the drive, the characters in folder names, backslash characters between folder names, and the characters in the file name itself.


To work around this issue, try any of the following workarounds.

Workaround 1: Reduce the character count

  • Rename the file so that it has a shorter name.
  • Rename one or more folders that contain the file so that they have shorter names.
  • Move the file to a folder that has a shorter path name.

Workaround 2: Manually access, open, and repair

  1. Start Word, Excel, or PowerPoint.

  2. On the File tab, select Open > Browse to locate the damaged file.

  3. Select the file, select the Open menu at the bottom of the window, and then select Open and Repair.

This option repairs the damage to the file, and then opens the file. After you repair the document, workbook, or presentation, it’s important to verify that the issue has been resolved successfully. To do this, begin working on the file, and make sure that everything is working as expected.

Workaround 3: Change file format and resave

You might be able to rescue a damaged file by resaving it in a different file format, and then reverting it to the original format. This example uses Word.

Step 1: Save the file to another format

  1. Start Word.

  2. On the File menu, select Open, and then locate and open the damaged file.

  3. On the File menu, select Save as > Browse.

  4. Navigate to the file location that you want to save in.

  5. On the Save as type list, select the desired file format. For example, select Rich Text Format (*rtf).

  6. Select Save, and then select File > Close.

Step 2: Resave the file as a Word document

  1. Select File > Open.

  2. Select the new file that’s saved as a Rich Text File, and then select Open.

  3. Select File > Save as.

  4. On the Save as type list, select Word Document.

  5. Rename the file, and then select Save.

You have to do this only one time to make sure that the document will now function correctly on your device. However, keep in mind that by saving the file as a new document, you are creating a different file. To avoid confusion, name the new file something distinctive, and archive or delete the damaged version. By doing this, you won’t accidentally re-open the original file that hasn’t been reformatted.

Workaround 4: Open unrecognized file format

If you can rule out file corruption as the culprit, check for file associations and unrecognized file formats. Sometimes, a file won’t open on your device because the device that the file was created on used software that your device doesn’t have.

Office 365 Won't Update

For example, in Word, you want to view a PDF file that’s attached to an email message. However, you don't have a PDF viewer installed. Therefore, your device doesn’t know what program to open to view the file. In this case, you can change the format of the file to match a program that you do have installed.

  1. Save the attachment to your computer. To do this, select the down arrow next to the attachment in the message, select Save as, navigate to the desired location, and then select Save.

  2. On the File menu, select Open > Browse to locate the file.

  3. Right-click the file, point to Open with, and then select a different program to open the file.

  4. If the desired program is not on the list, select “Choose another app” to locate a different program.


    If this works, and you would like the selected program to always open this type of file, select the Always use this app to open .docx files (for example) check box.

For more information about file formats and how to manage them, see Learn about file formats.

Workaround 5: Clear some disk space

You might not be able to open a new file or save a file to your device if you’re running out of space on the hard disk. On a full disk, much of the space is being used up by temporary, duplicate, and unnecessary items. The fastest and easiest method to free up space on a hard disk is to use the Disk Cleanup app that’s included in Windows.

  1. Select Search, and type Disk Cleanup.

  2. In the results list, select Disk Cleanup.

  3. A dialog box opens and provides options to delete unnecessary files. Select the check box next to each category of items that you want to delete from your device, and then select OK. Everything in this list can be deleted safely.

  4. When you are prompted, confirm that you want to permanently delete the unnecessary files.

The following files types are examples of removable items that you might see in the Disk Cleanup list:

  • Windows Update: Recent files that were downloaded from Windows Update (selecting these does not remove currently installed update versions)
  • Downloaded Program Files: Unnecessary program files, often related to the program installation
  • Temporary Internet Files: Files saved automatically by web browsers when you visit websites
  • Windows Error Reporting: Error reporting files that are created by the system
  • Recycle Bin: Any files that are stored in the Recycle Bin that you have not manually deleted
  • Temporary files: Other temporary files that are created by programs or web browsers
  • User file history: Files that record your browsing history (websites that you accessed, search results, and so on)
