ATTENTION! Before continuing on to install the Mso.dll library, you need to download the library. If you have not downloaded it yet, download it before continuing on to the installation steps. If you are having a problem while downloading the library, you can browse the download guide a few lines above.

Method 1: Installing the Mso.dll Library to the Windows System Directorylink

  1. The file you are going to download is a compressed file with the '.zip' extension. You cannot directly install the '.zip' file. First, you need to extract the dynamic link library from inside it. So, double-click the file with the '.zip' extension that you downloaded and open the file.
  2. You will see the library named 'Mso.dll' in the window that opens up. This is the library we are going to install. Click the library once with the left mouse button. By doing this you will have chosen the library.
  3. Click the 'Extract To' symbol marked in the picture. To extract the dynamic link library, it will want you to choose the desired location. Choose the 'Desktop' location and click 'OK' to extract the library to the desktop. In order to do this, you need to use the Winrar program. If you do not have this program, you can find and download it through a quick search on the Internet.
  4. Copy the 'Mso.dll' library you extracted and paste it into the 'C:WindowsSystem32' directory.
  5. If you are using a 64 Bit operating system, copy the 'Mso.dll' library and paste it into the 'C:WindowssysWOW64' as well.
    NOTE! On Windows operating systems with 64 Bit architecture, the dynamic link library must be in both the 'sysWOW64' directory as well as the 'System32' directory. In other words, you must copy the 'Mso.dll' library into both directories.
  6. First, we must run the Windows Command Promptas an administrator.
    NOTE! We ran the Command Prompt on Windows 10. If you are using Windows 8.1, Windows 8, Windows 7, Windows Vista or Windows XP, you can use the same methods to run the Command Prompt as an administrator.
    1. Open the Start Menu and type in 'cmd', but don't press Enter. Doing this, you will have run a search of your computer through the Start Menu. In other words, typing in 'cmd' we did a search for the Command Prompt.
    2. When you see the 'Command Prompt' option among the search results, push the 'CTRL' + 'SHIFT' + 'ENTER
      3. ' keys on your keyboard.
    3. A verification window will pop up asking, 'Do you want to run the Command Prompt as with administrative permission?' Approve this action by saying, 'Yes'.
  7. Paste the command below into the Command Line window that opens and hit the Enter key on your keyboard. This command will delete the Mso.dll library's damaged registry (It will not delete the file you pasted into the System32 directory, but will delete the registry in Regedit. The file you pasted in the System32 directory will not be damaged in any way).
    %windir%System32regsvr32.exe /u Mso.dll
  8. If you are using a Windows version that has 64 Bit architecture, after running the above command, you need to run the command below. With this command, we will clean the problematic Mso.dll registry for 64 Bit(The cleaning process only involves the registries in Regedit. In other words, the dynamic link library you pasted into the SysWoW64 will not be damaged).
    %windir%SysWoW64regsvr32.exe /u Mso.dll
  9. In order to cleanly recreate the dll library's registry that we deleted, copy the command below and paste it into the Command Line and hit Enter.
    %windir%System32regsvr32.exe /i Mso.dll
  10. If you are using a 64 Bit operating system, after running the command above, you also need to run the command below. With this command, we will have added a new library in place of the damaged Mso.dll library that we deleted.
    %windir%SysWoW64regsvr32.exe /i Mso.dll
  11. If you did the processes in full, the installation should have finished successfully. If you received an error from the command line, you don't need to be anxious. Even if the Mso.dll library was installed successfully, you can still receive error messages like these due to some incompatibilities. In order to test whether your dll issue was fixed or not, try running the program giving the error message again. If the error is continuing, try the 2nd Method to fix this issue.

  3. Copy the Mso.dll library.
  4. Paste the dynamic link library you copied into the program's installation directory that we just opened.
  5. When the dynamic link library is moved to the program installation directory, it means that the process is completed. Check to see if the issue was fixed by running the program giving the error message again. If you are still receiving the error message, you can complete the 3rd Method as an alternative.

Method 3: Uninstalling and Reinstalling the Program That Is Giving the Mso.dll Errorlink

  1. Open the Run window by pressing the 'Windows' + 'R' keys on your keyboard at the same time. Type in the command below into the Run window and push Enter to run it. This command will open the 'Programs and Features' window.

Sharing another problem and resolution I came across.

Recently, staff started complaining about Mail Merge crashing at the point of selecting a data source use. It was easily recreatable, and caused this event viewer error:

Excel Crash Mso Dll

Faulting application name: WINWORD.EXE, version: 14.0.7113.5001, time stamp: 0x52866c04

Report Id: 3bf6bbe2-70da-11e6-bd32-b8763fabbff5

Pretty standard for a crash. In our environment, we had changed from Lync 2010 to Skype for Business 2016, and installed Skype for Business through the Office 2016 installer rather than standalone, to make future Office product updates easier (Skype for Business standalone won’t co-exist with an Office 2016 suite install).

For some reason, this upgrade process has broken the mail merge function for Microsoft Word. The quick fix was to do a repair of the Office 2010 suite after the Office 2016 install, and mail merge worked again.

It’s worth noting that a computer that had Office 2010 suite and Office 2016 (Skype for Business only) worked fine, it was only if Lync 2010 was installed first and then removed, then Office 2016 installed.
