-If you want to dump breakpad symbols you also need to do this (you are free to
-skip this step if you don't know what it is):
-
-1. Get a copy of `msdia80.dll` and put it in
-   `C:\Program Files\Common Files\Microsoft Shared\VC\`.
-2. As Administrator, run:
-   `regsvr32 "C:\Program Files\Common Files\Microsoft Shared\VC\msdia80.dll"`.

 console or other terminals.
