Cannot use qdoc on Windows 7, Windows 8, Windows 8.1

Depending on the Windows version and whether using online or offline installer it seems to be impossible to use qdoc on Windows.

On Windows 7 you end up with a message box

---------------------------
qdoc.exe - System Error
---------------------------
The program can't start because api-ms-win-core-sysinfo-l1-2-0.dll is missing from your computer. Try reinstalling the program to fix this problem. 
---------------------------
OK   
--------------------------- 

(seems like qdoc was built on a later Windows version that does provide this lib by default)

Some installation end up with 'missing libclang.dll' (seems to be the case for 5.11.2 online installer - there qdoc is pretty small compared to 5.11.1 - about 1MB vs. ~42MB - so, probably dynamically linked)

Note: On Win7 I've got api-ms-win-core-sysinfo-l1-1-0.dll (all these libs have the 1-1-0 pattern while on Windows 10 they're all having 1-2-0).
