If when you try to open a program on your Windows computer you receive an error message The program can’t start because api-ms-win-crt-runtime-l1-1-0.dll is missing from your computer,it either means that Universal CRT, which is part of the Visual C++ Redistributable has either failed to install properly or that the api-ms-win-crt-runtime-l1-1-0.dll file has gone missing or become corrupted.
You may receive this error when trying to open some Adobe applications, SmartFTP software, Skype, Autodesk, Corel Draw, Microsoft Office, XAMPP, and so on.
DLL stands for Dynamic Link Libraries and are external parts of applications that run on Windows or any other operating systems. Most applications are not complete in themselves and store code in different files. If there is a need for the code, the related file is loaded into memory and used. If the OS or software is not able to find the concerned DLL file, or if the DLL file is corrupted, you could receive a DLL file is missing message.

Repair installed Visual C++ 2015 Redistributable package
If you have already installed Visual C++ 2015 Redistributable package, but you receive the error, you might need to repair the program. To do this, open Control Panel and go to “Programs and Features” section. Find out Microsoft Visual C++ 2015 Redistributable (x64) [for 64-bit machine] > right-click on it > select Change button > click on the Repair button.
Re-register the DLL file
If the DLL file is present on your computer, but you still receive this error message, you may need to re-register the DLL file.
If the DLL file is missing, then downloading the missing dll file from the internet and pasting it to a particular place is not the actual solution. You can try that method, but you may not get any positive result from it.
Update for Universal C Runtime
