Connection reset when running installer under php 7.1.x 7.2.x for Windows x64.
no problem with php 7.0.x or below
I think this caused by php 7.1 new feature:
''Implemented safe execution timeout handling, that prevents random crashes after "Maximum execution time exceeded" error.''
see http://php.net/ChangeLog-7.php#7.1.0 line 8
because php in windows slower than linux so execution timeout must be increced
