In your Windows 10 computer, one of the following errors may occur when you launch a 3rd party program:
VCRUNTIME140.dll is one of the runtime libraries of Microsoft Visual Studio (VC++) 2017 or 2015. VC++ runtime libraries are DLL files required to run programs compiled with Microsoft VC++ / Visual Studio suite. Software vendors usually include the runtime libraries in the setup packages since many versions with the same DLL file name can exist. Here is the list of some Visual C++ runtime library files:
Option 1: Reinstall the affected program
If you’re receiving the “VCRUNTIME140.dll is missing” error or any error referencing one of the above runtime modules, the best way to fix the problem is by reinstalling the affected software. For instance, Mozilla Firefox uses this runtime module and has a copy of the file in the Firefox program folder. Similarly, OneDrive has a copy of the file in its own program folder.
Option 2: Repair Visual C++ 2015 Redistributable via Apps & Features
Windows Update regularly downloads Microsoft Visual Studio (VC++) 2015 (x86) runtime libraries in your Windows 10 computer. So, another way to fix the error is to repair the Microsoft Visual C++ 2015 redistributable (x86) via Apps & Features in Windows 10.
- Click Start, Settings. Click Apps & Features.
- Scroll down and select the entry “Microsoft Visual C++ 2015 Redistributable (x86)”
- Click Modify.
- In the Setup screen, click Repair.
This repairs the VC++ redistributables (runtime libraries). See if you can launch that 3rd party program successfully now.
Note that by default, Windows Update only downloads and installs the VC++ 2015 redistributable x86 version in Windows 10, as seen in Apps & Features (Settings) or Programs and Features in the classic Control Panel.
Option 3: Download Visual C++ Redistributable from MS Download Center
If the problem persists even after repairing it, you may try downloading the Microsoft Visual C++ 2015 Redistributable from the Microsoft Download Center. For other versions of the VC++ runtimes, see Microsoft article The latest supported Visual C++ downloads. Be sure to download the correct version and bitness (32-bit vs 64-bit) of the runtimes matching the version (VC++ 2015 vs 2017) and bitness of the program you’re trying to run.
