How to fix api-ms-win-crt-runtime-l1-1-0.dll is missing error in Microsoft Office

I’m currently running the Windows 10 64 bit operating system, so I decided to have Microsoft Office installed, because I needed to prepare some presentations for my college and other things related with text edition and presentation. After the installation, I tried opening existing documents and creating documents to no avail, all I got was an error message to the effect that api-ms-win-crt-runtime-l1-1-0.dll is missing and cannot be found on your system. I checked out the system folder and the api-ms-win-crt-runtime-l1-1-0.dll file was nowhere to be found. I thought it was a compatibility issue between the recent and the older Microsoft Office, but I didn’t find anything pointing to that fact on the internet and when I called Microsoft support they informed me that it shouldn’t be the case and that the error was caused by the absence of the file on my system. Since they didn’t have any solution for me, I decided to find a solution on my own.

So, I’ve downloaded the missing library from I ascertained the genuineness of the file by making comparisons between the MD5 and SHA1 file sum and the original. This simple guide allowed me to run Microsoft Office on my Windows 10 64-bit without api-ms-win-crt-runtime-l1-1-0.dll is missing error. Hope it will help you too.
