- After upgrading from various previous versions of Excel to 2013. We now get random crashes, the latest was the following: Problem Event Name: APPCRASH Application Name: EXCEL.EXE Application Version: 15.0.4569.1504 Application Timestamp: 52c5fc07 Fault Module Name: mso.dll Fault Module Version: 15.0.4569.1506 Fault Module Timestamp: 52e0dcca Exception Code: c0000602 Exception Offset.
- The Mso.dll file is a dynamic link library for Windows 10, 8.1, 8, 7, Vista and XP. You can fix 'The file Mso.dll is missing.' And 'Mso.dll not found.' Errors by downloading and installing this file from our site.
The crash does occur on specific workbooks that contain macros (not Add-Ins - but my Excel starts up with many add-ins loaded - does not crash on most files even those with Macros). The files that crash do not normally crash, only once in a while, but once they crash they will not open without crashing UNTIL: I have someone else open the file. I won't even begin to list the number of 'fixes' I've attempted to try to overcome this issue, all to no avail (most of them submitted online by other users and admins experiencing the same issue). However, both users still report that their Excel keeps crashing. Faulting application name: EXCEL.EXE, version: 15.0.4701.1001, time stamp: 0x54e30a7b Faulting module name: mso.dll, version: 0.0.0.0, time stamp: 0x54d9bfd6 Exception code: 0xc0000602 Fault offset: 0x011aee88 Faulting process id: 0x1990 Faulting application start time: 0x01d0773e764ce473 Faulting application path: C: Program Files Microsoft.
Today I got a support ticket from our one and only (so far) Office 2010 user. Her Excel was crashing when she tried to sort data. This was what I found in the Event Viewer:
Faulting application excel.exe, version 14.0.5130.5003, stamp 4d3061c8, faulting module mso.dll, version 14.0.5128.5000, stamp 4caf84cd, debug? 0, fault address 0x006a46e2.
A bit of googling suggested she wasn’t alone, and that a lot of people with the issue were editing .xls files (97-2003) in Compatibility Mode when the crash occurred (sometimes repeatedly). There was some suggestion that saving in .xlsx would stop the crashes, and it did.
I’m sure good ‘ol MS will have a fix for this at some point. I’ll update this post if I get the time to search for a workaround that is better than “save it in the new format”.

How to Fix Mso.dll Errors?link
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
- 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.
- 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.
- 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.
- Copy the 'Mso.dll' library you extracted and paste it into the 'C:WindowsSystem32' directory.
- 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.
- 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.
- 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.
- When you see the 'Command Prompt' option among the search results, push the 'CTRL' + 'SHIFT' + 'ENTER ' keys on your keyboard.
- 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'.
- 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
- 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
- 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
- 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
- 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.
Method 2: Copying The Mso.dll Library Into The Program Installation Directorylink
- First, you need to find the installation directory for the program you are receiving the 'Mso.dll not found', 'Mso.dll is missing' or other similar dll errors. In order to do this, right-click on the shortcut for the program and click the Properties option from the options that come up.
- Open the program's installation directory by clicking on the Open File Location button in the Properties window that comes up.
- Copy the Mso.dll library.
- Paste the dynamic link library you copied into the program's installation directory that we just opened.
- 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
- 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.
appwiz.cpl
- The Programs and Features screen will come up. You can see all the programs installed on your computer in the list on this screen. Find the program giving you the dll error in the list and right-click it. Click the 'Uninstall' item in the right-click menu that appears and begin the uninstall process.
- A window will open up asking whether to confirm or deny the uninstall process for the program. Confirm the process and wait for the uninstall process to finish. Restart your computer after the program has been uninstalled from your computer.
- After restarting your computer, reinstall the program that was giving the error.
- You can fix the error you are expericing with this method. If the dll error is continuing in spite of the solution methods you are using, the source of the problem is the Windows operating system. In order to fix dll errors in Windows you will need to complete the 4th Method and the 5th Method in the list.
Method 4: Fixing the Mso.dll error with the Windows System File Checkerlink
- 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.
- 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.

- Paste the command in the line below into the Command Line that opens up and press Enter key.
sfc /scannow
- The scan and repair process can take some time depending on your hardware and amount of system errors. Wait for the process to complete. After the repair process finishes, try running the program that is giving you're the error.
Method 5: Getting Rid of Mso.dll Errors by Updating the Windows Operating Systemlink
Most of the time, programs have been programmed to use the most recent dynamic link libraries. If your operating system is not updated, these files cannot be provided and dll errors appear. So, we will try to fix the dll errors by updating the operating system.
