Fix: api-ms-win-crt-runtime-l1-1-0.dll is missing on Windows 7, 8 and 10


You have come to the site where I will give the most detailed answer that will contain several options that will help you solve the problem with this error!

The windows operating system, in its work with various applications, uses libraries which end in .dll and they are located in the system folder c: \ windows

One of these libraries is our api-ms-win-crt-runtime-l1-1-0.dll file


This library is included in the Microsoft Visual C ++ software package and before proceeding to solving this problem, you must first solve the main options for which this error occurs and, based on the answers already received, proceed to one or another solution to the problem!

  1. If you have an error with api-ms-win-crt-runtime for the first time, you most likely have not installed the Microsoft Visual C ++ package
  2. If you have an application or a program that has stopped running despite the fact that it worked some time ago, then most likely the problem lies in the fact that a conflict has arisen or the file has been damaged as a result of the installation of some programs or viruses

Now let’s get down to business!

Installing Microsoft Visual C ++

In most cases, the error often occurs for two reasons, either there is no such library, or it is damaged! In these cases, the best solution would be to reinstall Microsoft Visual C ++

But in order to make sure of this, I advise you to check which version you have on your computer:

  1. Open Start
  2. Control Panel
  3. The installing and deleting of programms
  4. and find in the list of Microsoft Visual C ++ programs

Microsoft Visual C ++

After you have made sure that you have Microsoft Visual C ++ or not, I would advise you to uninstall it (if it is) and then download Microsoft Visual C ++ from the official Microsoft website. At the moment, the latest version is 2019, after installing it, restart your computer and test your application. If this option did not work, then move on to another option.

Windows Update KB2999226

Further, the most common problem may be the presence, or rather the lack of updates on windows, this problem is solved quite simply!

  1. start
  2. Control Panel
  3. Windows update
  4. click the button – Check for updates

after installing the updates, restart the computer and check the operation of your program, if this option did not help, try updating windows manually by downloading the update KB2999226 update package from the official microsoft website.

After installation, reboot and check the program again, if this option did not work, go to the next one!

Reinstall an app or game

If after two options you still fail to start the application that crashes with the api-ms-win-crt-runtime-l1-1-0.dll error , I advise you to reinstall your application or game! And here the question is not that there are no other options, but that at the moment you already have the latest version of Microsoft Visual C ++ and have the latest Windows updates and everything should work 99%, so just reinstall your application that it is anew picked up all the files and libraries for full work.

Standard ways to treat all Windows errors

Foreword! Further, there will already be radical ways to solve this problem, which are standard for any error that did not dare in the first three options. Therefore, make sure you did the first three options exactly!

Registering files in the system

This method is radical, but you must know it! To do this, we need to download the api-ms-win-crt-runtime-l1-1-0.dll file itself and put it in the folder:

  • C: \ Windows \ SysWOW64 or folder
  • C: \ Windows \ System32

then use the regsvr command (read the article on how to register libraries with regsvr32)

System File Checker Tools

This is a standard utility that checks system files and if they are different, then it replaces them, in order to describe how this utility works, read my article on working with sfc / scannow

Virus check

If you don’t have any antivirus installed on your computer, then I won’t be surprised that you and not only have a problem with this file! I always advise you to download Kaspersky antivirus from the official website, especially for one month it works for free! check the system and remove all viruses that it finds!

Reinstalling the OS (operating system!)

I will not even offer other methods because they are not very effective, so just reinstall your windows, if the work of this application is very critical for you, or write to me by mail, I will try to help you!
