Can't install vc_redist.x64 [Unknown Error]

Good evening everyone,

I'm currently having a hard time trying to install Microsoft Visual C++ Redistributable (x64)

It all started when this error-message appeared for no reason. api-ms-win-crt-runtime-l1-1-0.dll missing

So I jumped into google and quickly found out my Laptop needs the current vc_redist update. Sadly no matter what I try I always get the following error: 0x80240017 - Unknown Error

This error is bugging me for a long time already, I really hope you guys can help me any further.

Thanks for any help in advance!

Cheerz~
