How to Install api-ms-win-crt-runtime-l1-1-0.dll File?

iTunes is an easy and reliable way to enjoy favorite music and podcasts as well as to discover new ones; therefore, there’s no surprise that many Windows users install the media library on their system. iTunes for Windows is used by those who own iOS products but do not have a Mac. Not only it allows them to synchronize their devices but it also an indispensable piece of software for purchasing digital content from the Apple’s store. The case for using iTunes on a PC is clear – it’s the only way to access media content that comes from Apple. Despite the convenience of using iTunes on Windows, sometimes the user experience is spoiled by a message informing them that api-ms-win-crt-runtime-l1-1-0.dll can’t be found. The article details how to resolve this issue.

What is Runtime File and Why it is Missing?

What prevents iTunes from launching is the lack of the Dynamic Link Libraries (DLL) file. Programs such as iTunes, Skype, and Microsoft Office store some of its code in DLL files that are loaded into memory whenever a program is launched. If a DDL file is corrupted or missing, a program cannot be started. Fortunately, the issue can be resolved fairly easy.

What Should Be Done

To resolve the problem, one shouldn’t reinstall iTunes despite the urging of the system error message.

Instead, it is necessary to download the missing DLL file. A warning is due at this point: iTunes user should never download the file from any external website. It has to do with the fact that DDL files distributed by third-party websites can pose a substantial security threat to the system. Furthermore, they are rarely up-to-date, which also makes their use unsafe. Therefore, it is necessary to obtain the DDL file either through Windows update or by downloading Visual C++ Redistributable for Visual Studio.

Windows Update Option

To obtain the file via Windows Update, do the following:

  1. In the search box, type Update and select the Check for Updates result;
  2. In a window that opens, click on the Check for Updates button;
  3. Restart the PC;
  4. Repeat the previous steps until there are no available updates;
  5. Launch iTunes.

Usually, Windows downloads and installs the missing DLL file along with updates; however, if after trying this option, the issue is not resolved it is recommended to follow the second route.

Download Visual C++ Redistributable for Visual Studio

To download the DDL along with Visual C++ Redistributable for Visual Studio directly, do the following:

  1. Go to Microsoft download page;
  2. Click on the Download button;
  3. Select the system type and click on the Next button;

(To check the type of Windows, enter system in the search box and select the System Information option);

  1. After downloading is successfully completed, double-click the .exe file and follow the instructions in the installer;
  2. Restart the PC;
  3. Launch iTunes.

In rare cases, the two solutions described above fail to resolve the issue. Those who cannot launch iTunes after trying the two methods should upgrade their PC to Windows 10, which is the latest version of Windows OS. Since the DDL file is the part of the new OS, the problem should be gone.
