“The program can’t start because MFC120u.dll is missing,” “MFC120u.dll is missing from your computer,” “MFC120u.dll is missing” … One of the most common Windows errors is related to the MFC120u.dll file. Apparently, the error in question appears when trying to run certain programs: Ableton Live, Corel Draw, Visual Studio, Skype… The good news is that the error has an easy solution, which we’ll see below.
Solution to the error MFC120u.dll is missing from your computer in Windows 10, 8, and 7
Like most DLL libraries, its execution depends entirely on the Microsoft Visual Studio C++ library. The first step to resolve the error is to reinstall the library using the various packages for 32- and 64-bit computers .
Before proceeding with the download, the first thing we’ll need to do is determine our PC’s architecture. To do this, right-click the Windows icon in the Start menu. Next, click System; under System Type, Windows will display the architecture type (32-bit or 64-bit) .
- Download Visual C++ for Windows
The next step is to download the library from the Microsoft website. The x86 package is for 32-bit computers , while the x64 version is for 64-bit computers. Once downloaded, the installation process is similar to that of other programs. Finally, we’ll restart the computer for the changes to take effect.
Download MFC120u.dll to manually install the file
Another solution if the above method does not work is to download the file in question and install it manually in its corresponding directory in Windows.
- Download MFC120u.dll 32-bit
- Download MFC120u.dll 64-bit
With the file downloaded, we will go to the following path to paste it into the root of the folder:
- Local disk C:/Windows/System32
If you have a 32-bit computer, you’ll need to copy the file to the SysWOW64 folder, which is located in the same directory—specifically, in /Windows .
Move the MFC120u.dll file to the program’s execution folder
If the above does not work, the next step is to move the library to the program’s execution folder, which can be accessed by right-clicking on the program icon in question and clicking on Open file location , as can be seen in the following screenshot:
Now we just have to paste the library into the root of the folder.
And if none of the above works…
We’ll need to use the Windows command prompt, better known as CMD. Simply type its name in the Windows search box, then right-click on the program to run it with administrator privileges .
With the machine open, we will write the following command:
- sfc /scannow
Finally, the program will run a diagnostic tool that will help you find and repair system errors. However, the process may take a few minutes , depending on the hard drive’s read and write speed. For the changes to take effect correctly, restart your computer.
