Öncelikle merhabalar sorunumu yazıyorum çözebilen kişiye cuzi miktarda olsa ödemesini vereceğim.
Bir yazılım kurulumu sırasında token ve key sistemi yapılmış tokeni alıp x bir websitesinde 1 kredi karşılığında token keyini farklı bir key'e dönüştürüyor ve bizde yazılımı kurmak için olan yere keyi giriyoruz kurulum devam ediyor.
Bana bu key'in nasıl verildiğini anlayacak ve bunu söyleyecek birisine ihtiyacım var bu bilgiye nazaran ödeme yapacağımdan şüpheniz olmasın. Aşağıya .bat dosyasındaki kodları yazacağım.
