Some Windows users are viewing an error message called The program can’t start because api-ms-win-crt-runtime-l1-1-0.dll is missing from your computer. There could be several reasons why you might get this DLL file missing error while opening an app on Windows 10 computer.

If there was a recent adware attack and some system files got changed, there is a chance of getting this particular error message. Similarly, an identical error message may appear if you download and install software from an untrusted website that contains malware.

Instead of heading to some dedicated websites to download a particular DLL file, it is recommended to go through the following troubleshooting steps to eliminate this error first.

1. Download Microsoft Visual C++ Redistributable Update 3 RC

Whether you are using Windows 7, 8, or 10, you must download this package from the official Microsoft website and install it.

To download the package, you need to know your system architecture (32-bit or 64-bit). If you do not know that already, open This PC, right-click on an empty space and select the Properties option.

Now, check the System type. If x64 is visible, you have a 64-bit system, whereas x86 defines a 32-bit system.

After installation, restart your computer and check if it solves the issue or not.

2. Repair the Installed Visual C++ 2015 Redistributable Package

1: Search for Control Panel in the Taskbar search box, and click on the individual result to open Control Panel on your computer.

2: Click on the Uninstall a program option. If you cannot find it, make sure the View by is set as Category.

3: Find Microsoft Visual C++2015-2019 Redistributable (x64) or (x86) and click on it to select. In case you see both, select the first package and click the Change button.

It may ask for the administrator’s permission by showing the UAC prompt. You can click the Yes button to allow the app and wait for a few moments to allow the process to complete. Once done, restart your computer and check if the problem persists or not.

3. Update Universal C Runtime

At times, Windows Update might not download the required package due to some misconfiguration. To fix that, you may download the update package for Universal C Runtime in Windows from the official Microsoft website.

It is a basic download and installation step. However, as you are using Windows 10, it is recommended to download the Windows 8.1 package since there is no official release for Windows 10 yet (but it works).

4. Reinstall the Software

The ‘api-ms-win-crt-runtime-l1-1-0.dll is missing’ error may occur while opening any installed program, such as Google Chrome, Skype, Evernote, etc. When this error occurs, and if it is happening with only one specific app, you have to note the app name. You can check the app name in the title bar of the error message.

Then, you have two options – repair the installed software or reinstall it. As the repair option is not always available for all the apps, you have to make use of the second option. To repair an app, follow these steps-

1: Search for the Control Panel in the Taskbar search box and click on the individual result.

2: Set the View by as Category, and click on the Uninstall a program option.

3: Let’s say you want to repair the Microsoft Edge browser. For that, select the Microsoft Edge, and click on the Change option visible on the top menu bar. For some apps, you may view a dedicated Repair option instead of the Change button.

4: Then, click on the Repair button and wait for a few moments to complete the process.

1: Search for create a restore point in the Taskbar search box, and click on the respective search result to open the System Properties window.
