 If you didn't install Windows SDKs before, you need to install them now. To install the SDKs just open Telegram solution at **D:\TBuild\tdesktop\Telegram.sln** and on startup Visual Studio 2015 will popup dialog box and ask to download and install extra components (including Windows 7 SDK).
 
 If you already have Windows SDKs then find the library folder and correct it at configure's command below (like **C:\Program Files (x86)\Windows Kits\8.0\Lib\win8\um\x86**).

Either via the command line or File Explorer, rename the top-level src folder and move the inner src folder one level up.  This way, what was once breakpad\src\src\client is now breakpad\src\client, etc.
