Got an error for Barcode

Hi Hiroaki Miyashita,

Thank you for this dual generator plugins, your plugin was great for QR code, but i’m afraid can’t working well for the barcode.

I put this script for my template;

<? echo do_shortcode(' [barcode text ='.$current_user->number_reg.' height = 100 width = 2 transparency = 1]'); ?>

and the error says like this

Warning: require_once(Image/Barcode2/Writer.php): failed to open stream: No such file or directory in X:\wamp\www\engine\wp-content\plugins\barcode-qrcode-generator\Image\Barcode2.php on line 25

i’m using XAMMP with Apache 2.2.22, PHP 5.4.3

Thank you
