Trying to install a new payment addon - does not install

We have a payment addon in place, we created another one similar to the one we have, but when we click the install button it seems it has been installed, but it does not show up in the payment methods under Administration.
Is there something we need from CS-Cart for it to be allowed or something?

Hello

If we are to help you, you must show the addon package.

Does your module adds extra row to the cscart_payment_processors table? Please check it in the phpMyAdmin
