Missing api-ms-win-crt-runtime-l1-1-0.dll

I just started getting this message yesterday every time I started Altium.

The program can't start because api-ms-win-crt-runtime-l1-1-0.dll is missing from your computer. Try reinstalling the program to fix this problem.

"Try reinstalling the program to fix this problem" ?

I can tell you that reinstalling Altium did not fix the problem.

To fix the problem I installed Visual C++ Redistributable for Visual Studio 2015.

For Win 7 64 bit install vc_redistx64.exe

That's It !
