Application won't start (0xc000007b) with GTK+ and C

Question

I have written an really basic test application in C with GTK+ 3, but when I want to start this application I'm getting the following error:

The application was unable to start correctly (0xc000007b)

But Im getting this only with GTK+ 3.

My Code:

#include <stdio.h>
#include <gtk/gtk.h>

static void activate(GtkApplication *app, gpointer user_data) {
    GtkWidget *window;

    window = gtk_application_window_new(app);

    gtk_window_set_title(GTK_WINDOW (window), "Tutorial");
    gtk_window_set_default_size(GTK_WINDOW(window), 200, 200);
    gtk_widget_show_all(window);

}

int main(int argc, char **argv) {
    printf("Hello, World!\n");

    //printf("Ein akustisches Signal mit : (\\a)\a");
    printf("\nEin Backspace mit : (\\b) | \bx\n");
    printf("Ein Zeilenvorschub mit : (\\t) |\tx");
    printf("\n\tC\n\ti\n\ts\n\tt\n\ttoll\n");
    printf("\t   u\n\t   n\n\t   d\n");
    printf("\t   macht Spaß\n");

    //Kommentar 1
    /* Kommentar 2 */
    /*
     * Mehrzeiliges Kommentar
     */

    GtkApplication *app;
    int status;

    app = gtk_application_new("org.gtk.example", G_APPLICATION_FLAGS_NONE);

    g_signal_connect(app, "activate", G_CALLBACK(activate), NULL);

    status = g_application_run(G_APPLICATION(app), argc, argv);

    g_object_unref(app);

    return status;
}

It's loading 32 bit DLL's, but I'm using 64 bit cmake and 64 bit gtk library and I have a 64 bit system, so why It's using the 32 bit windows dll's — Nightloewe, Jul 04 '17 at 21:25

Ok, I fixed my own bug ^^

I set an GTK_BASEPATH in my system variables and the PATH variable to an old version of GTK (32 bit) and It used these files as library.
