Safest way is to install the ones with the application failing to run. As an example for AMD drivers it's C:\AMD\Win10-64Bit-Radeon-Software-Adrenalin-Edition-18.4.1-Apr26\Packages\Apps\VC15RTx64

Hi ,

Surely I am here to help you.

Follow these steps.

Firstly check your window and your Window should be Updated.

You may check your window version through this step

-Navigate to Windows Settings and click on Windows & Security.
- Next, tap on “Check for updates” and see if you find any updates available.

If Windows is updated and everything looks fine, try re-installing the particular program that is reverting api-ms-win-crt-runtime-l1-1-0.dll is missing.

Repair installed Visual C++ 2015 Redistributable package
-Now, if you already have the Visual C++ 2015 Redistributable package installed on your computer and still getting the error, there’s a high chance that it can be fixed by repairing the program.

-To do so, head over to Control Panel >> Programs and select Programs and Features.
-Right-click on Microsoft Visual C++ 2015 Redistributable and tap on Change >> Repair.
-Tap on Yes, when asked for confirmation by User Account Control, and follow the given instructions to complete the process.

Install Microsoft Visual C++ Redistributable Update
Register the DLL file:

-Type “cmd” in the Windows search bar and under Best match, right-click on Command Prompt app, and select “Run as administrator.”

-Now enter the following command in the CMD window and hit enter.Click on Yes when prompted by User Account Control.

Register all DLL files:
Wait until the process gets completed and then restart your PC and try to open the application that was causing the problem.

-Copy-paste the api-ms-win-crt-runtime-l1-1-0.dll file
-Open “This PC” and navigate to Local Disk (C:) >> Windows and click on the System32 directory.
-Now using the search option (given at the top-right corner of the screen) look for

api-ms-win-crt-runtime -l1-1-0.dll.
-And if you found the file available, copy and paste it into your pen drive.
Next, plug the drive on your computer and copy that file and head over to C:\Windows\System32\downlevel and paste it there, and that’s it.

Hope your problem get solved by following these steps.
