Did you try launching an application in your PC and instead received a DLL not found problem? DLL errors, specifically api-ms-win-crt-runtime-l1-1-0.dll error, can cause much frustration to the user. Performing a repair is not difficult. We will lay out how to fix this as you will see it here.
DLL is short for Dynamic Link Library. It is an essential part of applications and programs, and without it, these won’t run correctly. In Windows, an application is typically not an executable file, but it is regularly divided into various independent DLL files.
When you want to operate an application, the system will call on its relevant DLL files. If you need to know which specific DLL file a program uses, you can use some tools like Process Explorer.
Some of the common DLL files errors include xvid.dll, kernell32.dll, rundll32.dll, shell32.dll, wmp.dll, system32.dll, and many more. These files are often removed by accident when you uninstall a program. There can also be other reasons, such as a virus corrupting your computer.
