Recently, I need to create QR Code barcodes in my Java program. So I bought a Java barcode generator from However, I can not install this control in my computer! I tried many ways. But it just did not work! Another computer can run it smoothly. It's maybe just the problem of my computer. I bought one license. So does anyone bought products from and know about this? Anyone can help me? Great thanks to you in advance! I am really in a hurry. Because my boss asked me to finish my program this week. Help please!
