How to Fix api-ms-win-crt-runtime-l1-1-0.dll Missing?

You need to start by making sure your system is updated and everything functions correctly. Windows 10 computers should come with all the files required to run the program. Some other operating systems require an update for it to work in some cases.

Next, replace the missing files and make sure they’re installed correctly. Sometimes you can simply repair it or update the files. Other times, you might need to delete it and reinstall the program. 

Once you’ve completed all these steps, you should be able to relaunch the program that prompted the error without difficulty. 

Update Windows and Check for Damaged Files

The first thing you should do to address this error is update Windows. Ensuring the computer is up-to-date might take care of missing files or fix errors.

  1. Press Windows key + X.
  2. Choose Settings.
  3. Select Update and Security.
  4. Click Check for Updates.
  5. Wait for the updates to install.
  6. Click Restart Now.
  7. Wait for your computer to restart fully before doing anything else on it. 

Once Windows is fully updated, you should check to ensure you don’t have any corrupted files. Sometimes a program might have difficulty installing or running correctly if some system files are damaged. Use the SFC scan to see whether your system has errors.

  1. Press Windows key + X.
  2. Choose Windows PowerShell (Admin) and click Yes.
  3. Type “dism.exe /online /cleanup-image /restorehealth” without quotes and press Enter.Running-dism-command
  4. Type “sfc /scannow” without quotes.sfcscannow
  5. Press Enter.

When the process is done, you can see whether it found errors. If it can’t run, try to rerun it in safe mode. If it finds errors and can’t correct them, you either need to replace the damaged files with fresh copies from another OS or reinstall Windows.

If you haven’t updated your GPU drivers lately, you should also update them. It solved the issue for some users when the error appeared while launching a game. 

Try to Repair the Program

If you don’t want to reinstall the program right away, you can try to repair it. Sometimes this works, and it takes less effort than a complete reinstallation. 

  1. Press Windows key + X.
  2. Click Settings.
  3. Choose Apps.
  4. Scroll to Windows Visual C++ 2015-2019 Redistributable (x64).
  5. Click the entry.
  6. Click Modify.Microsoft-visual-c++2015-2019-modify
  7. Click Yes.
  8. Click Repair.
  9. Click Restart.
  10. Let the process complete and follow the prompts to complete the repair process.

Once you’re done, try using the program you opened when the error occurred. If it doesn’t appear again, you’re done and repairing the file worked. If it’s still appearing, then you need to completely delete the file, reinstall it, and register the DLL file, depending on what happens.

Try to Register the Missing DLL File

When a file misbehaves, sometimes using a utility that can register the file once more will fix the problem. The easiest way to do it is to register all the DLL files on your operating system again.

  1. Press Windows key.
  2. Type “cmd” without quotes in the search bar.
  3. Right-click Command Prompt.
  4. Choose Run as Administrator.
  5. Click Yes.
  6. Type the following command:
    for %1 in (*.dll) do regsvr32 /s %1register-missing-dll-file
  7. Press Enter

Let the program run until it’s done, then close the command prompt window. Try to see whether you can use the app without issues now that all the DLL files on your computer have been re-registered.

Update Universal C Runtime

Sometimes the Windows Visual C++ program doesn’t run properly without an update. Not all computers require the update, but it is a solution when the program detects errors. You can download the update directly from Microsoft.

Keep in mind that this is only feasible for computers running earlier versions of Windows like 8.1 or 7. 

  1. Navigate to the Update Download Page.
  2. Scroll down to the Download Center option.
  3. Click “Download the package now” on the line that corresponds with your operating system.download-the-packages
  4. Choose your language from the drop-down menu.
  5. Click Download.
  6. Save the file in a place where you can easily find it. 
  7. Navigate to the file when the download is complete.
  8. Open the downloaded program.
  9. Follow the prompts to install the update.
  10. Restart your computer when the installation is complete.

Once your computer has rebooted, try using the program that caused the error again. If it works this time, problem solved. If not, continue to try different solutions. 

Install an Updated Version of Visual Studio

You can download the latest version of Visual Studio for free from Microsoft. The latest version is newer than the version that often causes this error. You can have both versions on your computer, so installing this one shouldn’t cause any problems to install this one. 

  1. Navigate to the Visual Studio download page
  2. Click Free Download. The file will automatically be saved wherever your browser saves downloaded files by default.visual-studio2022-free-download
  3. Open the file when the download is finished.
  4. Click Yes.
  5. Click Continue. The installer will start preparing your computer for the installation.
  6. Click Continue.
  7. Click Continue again to confirm that you want to install the file without additional programs. The installation will start, but it can take a while to complete.
  8. Click “Not now, maybe later.”
  9. Click the X on the pop-up to close the window.
  10. Click Yes.
  11. Press X to close the installer.
  12. Restart your computer.

Try to use the program again to determine whether installing the updated version fixed its problem.

Removing  and Reinstalling Windows Visual C++ 2015-2019 Redistributable (x64)

At this point, your best bet is to remove the Windows Visual C++ from your computer. Once it’s gone, you can download a new version and hope that a fresh copy will take care of the problems. 

  1. Press Windows key + X.
  2. Choose Settings.
  3. Click Apps.
  4. Scroll down to Microsoft Visual C++ 2015-2019 Redistributable.
  5. Click on the entry.
  6. Click Uninstall.
  7. Click Uninstall.uninstall-microsoft-visual
  8. Click Yes.
  9. Click Uninstall on the pop-up.
  10. Click Close.
  11. Repeat steps 4-10 to remove any copies of the same program in Apps.
  12. Restart your computer.

Once the computer is back on, you can download a fresh copy of the file.

Remember not to remove any other Visual C++ programs. You shouldn’t have to remove and reinstall earlier versions. Just removing 2015-2019 Redistributable should work.

  1. Navigate to the download page.
  2. Choose your language from the drop-down menu.
  3. Choose Download.download-visual-c++
  4. Click the box next to the version that applies to the computer you’re using.
  5. Click Next. The program will be saved where your browser saves downloaded files.
  6. Navigate to the file and run it.
  7. Click the box to agree to the terms and conditions.
  8. Click Install.
  9. Choose Yes.
  10. Click Close.
  11. Restart your computer. 

All of the files associated with Visual Studio should be removed from your computer and replaced with fresh copies at this point.

If you still can’t get the error message to stop appearing, you may need to repair Windows or reinstall your operating system. Some say that upgrading to a newer version of Windows might help – but you should be able to run those programs on any compatible operating system. 

Ultimately, if removing and replacing the program doesn’t fix it, you may have a computer problem that needs to be examined by a licensed technician.
