To fix this error, you will have to apply some fixes to restore a missing or corrupted DLL file, such as re-installing or repairing Microsoft Visual C++, manually downloading and replacing the DLL file, updating Windows to restore the DLL file, repairing the corrupted DLL file using SFC and DISM commands and restoring Windows to a previous state. Since this DLL file belongs to Microsoft Visual C++, the root cause of this error can be missing Microsoft Visual C++ from Windows, or it needs to be repaired. Microsoft Visual C++ is a required component for Windows and can also be installed individually or through the Windows update utility.

1. Install or Repair Microsoft Visual C++ Redistributable

Since the api-ms-win-crt-runtime-l1-1-0.dll comes with the Microsoft Visual C++ Redistributable, we can start with reinstalling or repairing the Microsoft Visual C++ Redistributable. If you already have Microsoft Visual C++ Redistributable, you can try repairing it by following the instructions. If that does not work, then go for reinstalling it. However, If you don’t have Microsoft Visual C++ Redistributable, installing it will fix this error. To do so, follow the steps:

Re-install Microsoft Visual C++ Redistributable

2. Manually Download and replace the DLLL file

Another method to fix this issue is to download and replace the api-ms-win-crt-runtime-l1-1-0.dll file with the corrupted one. We can use this website to download any DLL file to replace with the corrupted one. To do that, follow the steps:

3. Update your Windows

If the issue is not fixed yet, another method you can try is downloading the available updates for your Windows. Since Microsoft Visual C++ is required to run various Windows programs and third-party applications, you can install it via the built-in Windows update utility. To do so, follow the steps:

4. Execute DISM and SFC Commands

DISM, or Deployment Image Servicing and Management, is an in-built utility that downloads the required files through the Windows update utility and replaces them with the corrupted ones.  The SFC or System File Checker is known to fix the system files, especially the DLL. It scans the protected system files and replaces them with a cached copy located in the compressed folder at %WinDir%\System32\dllcache. To fix this error, try executing DISM, and SFC commands one by one with the help of the following instructions.

5. Use a System Restore utility

If the issue is still there, the final and last solution is to restore the Windows version to an earlier state where you were not encountering this issue. To restore the Windows version, you will need a restore point created when the error was not occurring. If you don’t have any restore points, then you cannot follow this method, and we don’t recommend you reinstall or reset Windows for this little error. Instead, take a copy of the missing DLL file from your friends’ PC, computer, or laptop with the same system type. Then, paste it into the C:\Windows\System32. Follow the steps to restore your Windows version to its previous state:
