For our own product downloading script, do you guy know any software that we can use? I mean the downloading page where after customer order and we redirect them to download the product. If you know, please let me know. Thanks
I am not sure what you mean. Usually sites that sell downloadable content send a download link by email, after order is placed and payment is processed. What are you selling on your website?
If you're looking for a software to create download pages search Google for "download page creator", I think you'll find it for around 5 bucks or even less.
