api-ms-win-crt-runtime-l1-1-0-dll is missing

Question

Hello, as many other people I've recently encountered the "api-ms-win-crt-runtime-l1-1-0-dll is missing" issue. I've looked on a lot of forums, and tried most solutions that were provided, but none of them ended up working. The most common one involved typing a few commands in the admin command prompt, however when I attempt to use the command "DISM.exe /Online /XXX" it tells me that the XXX option is unknown, no matter what the XXX is. Also I saw a lot of people mentioning "Windows Modules Installer Worker", but it doesn't seem to exist on my computer. Is there anything else I can do to hopefully fix this?

I'm on Windows 8.1 x64

Thanks

Hi, Oscar_available,

1. If having issues running Dism.exe commands using Command Prompt try using PowerShell (Admin) instead.
2. Follow these steps to fix the issue.

Each Method/step below progresses to the next if the first does not fix any corrupted files that are found, etc.

Have you read this Microsoft information about repairing corrupt system files and errors?

"Use the System File Checker tool to repair missing or corrupted system files"

And these eightforums.com Tutorials are very detailed for problems resulting from SFC Scan:

"How to Run "SFC /SCANNOW" Command at Boot or in Windows 8 and 8.1"

http://www.eightforums.com/tutorials/3047-sfc-scannow-command-run-windows-8-a.html

Read this Section there in conjunction with the rest of the information they give in above link.

   Note

If SFC could not fix something, then run the command again to see if it may be able to the next time. Sometimes it may take running the sfc /scannow command 3 times restarting the PC after each time to completely fix everything that it's able to.

If not, then run the **Dism /Online /Cleanup-Image /RestoreHealth**command to repair any component store corruption,

Repair-WindowsImage -Online -CheckHealthRepair-WindowsImage -Online -ScanHealthRepair-WindowsImage -Online -RestoreHealth

Restart the PC afterwards, and try the sfc /scannow command again.

If still not, then try using OPTION ONE above to run the sfc /scannow command at boot

If still not, then you could do a refresh of Windows 8, or run a System Restore using a restore point dated before the bad file occured to fix it. You may need to repeat doing a System Restore until you find a older restore point that may work.

If still not, then you can use the steps in the TIP box in the OPTION THREE section to manually replace the files that SFC could not fix.

Hey,

So I've tried using Windows PowerShell instead but it gives me the exact same results : the DISM.exe command tells me that the Add-Package or the Cleanup-Image options are unknown, and when trying sfc /scannow it tells me that "the windows resource protection could not start the repair service". I'm pretty sure the issue is that Windows Modules Installer Worker is not on my computer, as most solutions require it.

I guess installing it would solve most issues? Do you know how I can do that? I cannot find any relevant information about it on Google.
