Answer 1

I have faced the similar issue in Windows Server 2012 r2. After lot of findings I found that mfplat.dll was missing which is related to Window Media Service.

Hence you have to manually install the features so that you can get dll related to window media service.

1. Turn windows features on or off
2. Skip the roles screen and directly go to Feature screen
3. Select "Desktop Experience" under "User Interfaces and Infrastructure"

After this all required dll of opencv would be available.
