Probably, you are already using a fairly well "run-in" Windows, but the error has disturbed you only now. In fact, the reasons for the error are quite simple, and we will discuss them now.

First, we need to point out what the api-ms-win-crt-runtime-l1-1-0.dll file is. First, this file is a dynamic link library (DLL). Files of this type can contain a huge number of functions inside them, which, it should be noted, can be used by several programs in the system at the same time. All in all, a fairly versatile file. Secondly, api-ms-win-crt-runtime-l1-1-0.dll is a file included with the Universal C Runtime for the Windows operating system.

So, the reasons for the error. Probably, the program or game you are launching tried to access the dynamic link library api-ms-win-crt-runtime-l1-1-0.dll, however, this task was not possible. It was this inability to gain access to the file that caused the above error message to appear.

However, what could have prevented access to the library? Quite a lot, actually. Let's take a look at what could have happened to the api-ms-win-crt-runtime-l1-1-0.dll file.

  • Direct damage to the required library.
  • Corrupted entries in the Windows operating system registry related to this file.
  • Hard drive problems such as bad blocks (or bad sectors).
  • Some software on the PC changed the version of the file or deleted it without the user's knowledge.
  • The file may be out of date and needs to be updated.

Api-ms-win-crt-runtime-l1-1-0.dll error: solutions

There are many methods you can use to get rid of the api-ms-win-crt-runtime-l1-1-0.dll missing error. In this article, we will provide you with as many as eight methods to consider. First, we will describe the most effective ones. Let's start.

Method # 1 Installing or updating Microsoft Visual C ++ 2015 on a PC

Let's start with the most obvious step when this error occurs - installing Microsoft Visual C ++. Previously, we indicated that the api-ms-win-crt-runtime-l1-1-0.dll file is a component of the C runtime. Therefore, this file should be in the 2015 Microsoft Visual C ++ Library Package.

You can download the installer for Microsoft Visual C ++ 2015 libraries directly from the official Microsoft website. As soon as you download the installer, run it and install the libraries, among which the discussed file will be located. In fact, you will be able to install api-ms-win-crt-runtime-l1-1-0.dll to your computer, if it has not already been done.

The note: remember that when downloading the installer file, you need to build on the bitness of your operating system. From the above link you will be able to find the 32 and 64 bit installer. If you try to install libraries of the wrong bitness, this can lead to possible problems.

Method # 2 Missing update

Unfortunately, there are times when certain libraries from Microsoft Visual C ++ 2015 are not installed correctly on users' systems. This is just a bug and nothing serious. Fortunately, Microsoft has released an update for the Universal C Runtime, KB2999226, which contains the missing api-ms-win-crt-runtime-l1-1-0.dll file.

So, follow this link to the downloads section of the official Microsoft website and download the KB2999226 update package from there. Please note that this update has been released for several versions of the Windows operating system, so you need to download the correct service pack for your system. If you try to install the package for a different OS version, then nothing will work or there will be some problems.

Method # 3 Reinstalling a running game or application

The api-ms-win-crt-runtime-l1-1-0.dll file missing error could also appear due to the fact that the problem lies in the application or game that you are trying to launch. There are many reasons why this can happen. For example, the game files were damaged and now they cannot interact with the required file. Or, for example, when installing an application / game, some complications occurred and the necessary files were not installed.

Either way, we recommend that you try reinstalling and then trying to start again. If everything went well this time, then the problem really was the game or the app. From this it follows that you will no longer see an error with the api-ms-win-crt-runtime-l1-1-0.dll file. At least the percentage of its appearance is extremely low.

Method # 4 Virus threats

Let's now try to approach the problem from a slightly different angle. There is a small chance that the api-ms-win-crt-runtime-l1-1-0.dll error was due to the interference of viruses that got into your system. Viruses could easily change the version of the file or, for example, change its functionality, which led to the problem when a program tried to access it (technically, games are also programs). Or viruses could even get rid of it, which is also rare, then the probability still exists.

In general, the impact of viruses on a file or system is a very possible reason behind the error. We recommend that you try to perform a full scan of the Windows operating system for malicious elements in it. Scanning can be done using Windows Defender or any other third-party antivirus. If you do find something, get rid of it and make sure your system is clean. Then try to launch the program and check if the api-ms-win-crt-runtime-l1-1-0.dll file missing error appears.

Method # 5 "Fix" Windows Registry

The application startup error could also occur as a result of corrupted entries in the Windows Registry that are directly related to the api-ms-win-crt-runtime-l1-1-0.dll file. The entries in the Windows Registry could be damaged under completely different circumstances: after user manipulations, as a result of exposure to viruses or malicious software, a bug in the operating system, etc. etc. Regardless of the reason, you need to try to restore the Registry entries.

Fortunately, you do not need to manually dig into the Registry entries, as any specialized third-party tool can do this for you. It should be mentioned that such programs do not guarantee a 100% result, but it is worth trying. For example, you can try using the software CCleaner. Another way to restore Windows Registry entries is to use a backup.

Method # 6 Integrating the file into the system

There is another method to solve the problem with this error - it is downloading and registering the file in the system. We strongly discourage doing this, as you can download from the Internet (at best) a file of the wrong version or something worse. However, if none of the above works for you, try it.

So, first you need to download api-ms-win-crt-runtime-l1-1-0.dll from the Internet. Be careful when downloading the file and only do it from trusted sources. After downloading the file, place it in the directory C / Windows / System32 and C / Windows / SysWOW64.

After placing the file in the required directories, right-click on Start and select "Command Prompt (Administrator)". Next, enter the command in the line regsvr32 / u api-ms-win-crt-runtime-l1-1-0.dll and press Enter. Then enter the command regsvr32 / i api-ms-win-crt-runtime-l1-1-0.dll and press Enter the same way.

After entering the commands, reboot the system, enter it and try again to run the program you need. If you find the required file and its version, then the error about the absence of api-ms-win-crt-runtime-l1-1-0.dll will be resolved.

Method # 7 Recovering system files

The error with the api-ms-win-crt-runtime-l1-1-0.dll file may have occurred due to corruption of the system files that directly interacted with this file. You can check this probability with the System File Checker.

This program is able to scan system files and then restore them. Its functionality can be used only through the Command Line, so you will have to call it. Right-click on Start and select "Command Prompt (Administrator)".

Having opened the command line, enter the command into it sfc / scannow and press Enter. The process of scanning and restoring system files will begin. After completing this operation, the SFC utility will tell you at the command line whether the damage was found and whether it was fixed. Close Command Prompt, restart your PC and try to run the program you want. The api-ms-win-crt-runtime-l1-1-0.dll error may have been fixed.

Method # 8 Using a restore point

Unfortunately, if none of the above helped you start the program and get rid of the api-ms-win-crt-runtime-l1-1-0.dll error, then there is only one thing left - using a restore point. The system should usually automatically create restore points when you install something on it.

So click Windows + S to call the search string. Then enter "Control Panel" in it. You will see the same classic Control Panel window, which cannot be accessed in simple ways, at least in Windows 8 and Windows 10.

Find the "Recovery" section in the Control Panel. Then click on the item "Start System Restore". Next, you need to select the restore point you need and start System Restore. Of course, select the system image that does not cause an error with the api-ms-win-crt-runtime-l1-1-0.dll file.
