If a particular DLL file becomes corrupted or is accidentally deleted, it could wreak havoc on how those programs, that are associated with it, are run. To fix it, you should replace your missing/damaged DLL files with fresh, clean and up-to-date ones.

  1. Option 1 – Automatically (Recommended)
    Use a repair tool to check various areas in your computer and replace ALL DLL files that are missing and/or damaged – even those you don’t know about! It will deal with issues related to system errors, critical system files and find the right fix for you.
  2. Option 2 – Manually
    System File Checker is a built-in tool to check for corrupt, damaged system files and manage to restore them if there’re any. However, this tool can only diagnose major system files, and won’t deal with damaged DLL, Windows Registry key, etc.

Option 1 – Automatically (Recommended)

Reimage (commonly known as Reimage Repair) is a computer repair software that can diagnose problems on your computer and fix them immediately.

Option 2 – Manually

To check and restore your system file might take time and computer skills. You will need to run numerous commands, wait for the process to complete, or risk your personal data.

Step 1. Scan corrupt files with System File Checker

System File Checker (SFC) is a Windows built-in tool to identify and repair corrupted system files.

1) On your keyboard, press the Windows logo key and R at the same time to open the Run box. Type cmd and press Ctrl+Shift+Enter to run Command Prompt as administrator.

Click Yes when prompted for permission to make changes to your device.

2) In the Command Prompt, type the following command and hit Enter.

sfc /scannow

3) System File Check will begin to scan all system files and repair any corrupted or missing ones it detected. This may take 3-5 minutes.

4) You may receive something like the following messages after the verification.

  • no errors
  • it fixed some errors
  • could not fix all errors
  • could not fix errors at all
  • ……

No matter what message you receive, you can try running dism.exe (Deployment Image Servicing and Management) to further scan the health of your PC.

Step 2. Run dism.exe

1) Run Command Prompt as admin and enter the following commands.

  • This command line will scan the health of your PC:
dism.exe /online /cleanup-image /scanhealth
  • This command line will restore the health of your PC:
dism.exe /online /cleanup-image /restorehealth

2) After the restore health process finishes, you may get some error messages.

  • If restore heath gave you errors, you can always try this command line. This will take up to 2 hours.
dism /online /cleanup-image /startcomponentcleanup
  • If you get Error: 0x800F081F with the restore health scan, reboot your PC and run this command line.
Dism.exe /Online /Cleanup-Image /AnalyzeComponentStore

Restart your PC after repairing the corrupt files and check if the error ‘api-ms-win-crt-runtime-l1-1-0.dll is missing’ persists.

Method 6: Copy the api-ms-win-crt-runtime-l1-1-0.dll file from your friends’ PC

If unfortunately, all the previous methods fail to help, you can copy the api-ms-win-crt-runtime-l1-1-0.dll file from a PC that runs the same Windows system as yours.

Part 1: Check your Windows system type and find a computer that runs the same system as yours.

Here’s how you can check the Windows type of computer:

  1. On your keyboard, press the Windows logo key to bring up the Search box.
  2. Type system information and then select System Information from the result.

  3. You should then see the system type of the computer.

Part 2: Copy the api-ms-win-crt-runtime-l1-1-0.dll file from the working computer and then paste it to the problem computer.

Here’s how you can find the dll file:

  1. On the keyboard of the working computer, press the Windows logo key and E at the same time to bring up the File Explorer. 
  2. Go to C:WindowsSystem32, then type api-ms-win-crt-runtime-l1-1-0.dll and press Enter. If it shows no results, go to C:WindowsSysWOW64 instead and search api-ms-win-crt-runtime-l1-1-0.dll again.

  3. Copy the api-ms-win-crt-runtime-l1-1-0.dll file if found and paste it into the same location as where you copy the file in your problem computer.

Note: Keep in mind that not every computer with the same system type has the DLL file you want to restore, so this method is not always successful either.
