Windows can blow me.

However, NSIS has the ability to launch other programs and wait on them, so I thought--- no prob, I'll call "mkdir". Except you can't call shell built-ins. So I wrote a DOS batch file wrapper around mkdir ...

@echo off
if !%1==! goto skipit
if exist %1 goto skipit
mkdir %1
:skipit

But for some reason, it doesn't work on Win9x and the "if exist" line doesn't work, thus causing mkdir to generate an error and freeze the installation process with an ugly black command box showing. I'm not going to pretend I'm a expert batch file programmer, nor do I want to be. They're sick. So, I wrote a little Win32 C program to do it .... no more ugly DOS window during the installation:

#include "stdafx.h"
int APIENTRY WinMain
(HINSTANCE hInstance, HINSTANCE hPrevInstance,
 LPSTR lpCmdLine, int nCmdShow)
{ CreateDirectory(lpCmdLine, NULL); return 0; }
