Methods to Fix the Proto_msn.dll Errors
ATTENTION! Before continuing on to install the Proto_msn.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 Proto_msn.dll Library to the Windows System Directory
- The file you will download is a compressed file with the ".zip" extension. You cannot directly install the ".zip" file. Because of this, first, double-click this file and open the file. You will see the library named "Proto_msn.dll" in the window that opens. Drag this library to the desktop with the left mouse button. This is the library you need.
- Copy the "Proto_msn.dll" library file you extracted.
- Paste the dynamic link library you copied into the "C:\Windows\System32" directory.
- If you are using a 64 Bit operating system, copy the "Proto_msn.dll" library and paste it into the "C:\Windows\sysWOW64" 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 "Proto_msn.dll" library into both directories.
- In order to run the Command Line as an administrator, complete the following steps.
NOTE! In this explanation, we ran the Command Line on Windows 10. If you are using one of the Windows 8.1, Windows 8, Windows 7, Windows Vista or Windows XP operating systems, you can use the same methods to run the Command Line as an administrator. Even though the pictures are taken from Windows 10, the processes are similar.
- First, open the Start Menu and before clicking anywhere, type "cmd" but do not press Enter.
- When you see the "Command Line" option among the search results, hit the "CTRL" + "SHIFT" + "ENTER" keys on your keyboard.
- A window will pop up asking, "Do you want to run this process?". Confirm it by clicking to "Yes" button.
- Paste the command below into the Command Line window that opens up and press Enter key. This command will delete the problematic registry of the Proto_msn.dll library (Nothing will happen to the library we pasted in the System32 directory, it just deletes the registry from the Windows Registry Editor. The library we pasted in the System32 directory will not be damaged).
%windir%\System32\regsvr32.exe /u Proto_msn.dll
- If you are using a 64 Bit operating system, after doing the commands above, you also need to run the command below. With this command, we will also delete the Proto_msn.dll library's damaged registry for 64 Bit (The deleting process will be only for the registries in Regedit. In other words, the dll file you pasted into the SysWoW64 folder will not be damaged at all).
%windir%\SysWoW64\regsvr32.exe /u Proto_msn.dll
- We need to make a new registry for the dynamic link library in place of the one we deleted from the Windows Registry Editor. In order to do this process, copy the command below and after pasting it in the Command Line, press Enter.
%windir%\System32\regsvr32.exe /i Proto_msn.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 Proto_msn.dll library that we deleted.
%windir%\SysWoW64\regsvr32.exe /i Proto_msn.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 Proto_msn.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 Proto_msn.dll Library to the Program Installation Directory
- First, you need to find the installation directory for the program you are receiving the "Proto_msn.dll not found", "Proto_msn.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 Proto_msn.dll library into the directory we opened.
- The installation is complete. Run the program that is giving you the error. If the error is continuing, you may benefit from trying the 3rd Method as an alternative.
Method 3: Uninstalling and Reinstalling the Program that Gives You the Proto_msn.dll Error
- Push the "Windows" + "R" keys at the same time to open the Run window. Type the command below into the Run window that opens up and hit Enter. This process 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.
- This method may provide the solution to the dll error you're experiencing. If the dll error is continuing, the problem is most likely deriving from the Windows operating system. In order to fix dll errors deriving from the Windows operating system, complete the 4th Method and the 5th Method.
Method 4: Fixing the Proto_msn.dll Error Using the Windows System File Checker
- In order to run the Command Line as an administrator, complete the following steps.
NOTE! In this explanation, we ran the Command Line on Windows 10. If you are using one of the Windows 8.1, Windows 8, Windows 7, Windows Vista or Windows XP operating systems, you can use the same methods to run the Command Line as an administrator. Even though the pictures are taken from Windows 10, the processes are similar.
- First, open the Start Menu and before clicking anywhere, type "cmd" but do not press Enter.
- When you see the "Command Line" option among the search results, hit the "CTRL" + "SHIFT" + "ENTER" keys on your keyboard.
- A window will pop up asking, "Do you want to run this process?". Confirm it by clicking to "Yes" button.
- After typing the command below into the Command Line, push Enter.
sfc /scannow
- Depending on your computer's performance and the amount of errors on your system, this process can take some time. You can see the progress on the Command Line. Wait for this process to end. After the scan and repair processes are finished, try running the program giving you errors again.
Method 5: Fixing the Proto_msn.dll Errors by Manually Updating Windows
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.
Since the methods to update Windows versions are different from each other, we found it appropriate to prepare a separate article for each Windows version. You can get our update article that relates to your operating system version by using the links below.
