Non standard Installation Wizard

Dear Tech Support WebAssist,

Recently I bought from you Power Store 3, upgrading my current Power Store 2. With one key intention/objective that I will use Power Store 3 for non credit card store payment transaction. For the time being, I need to receive only payment by check/money order, during check out sequences. However because during installing the program, "standard wizard" request us to have contact with credit card providers i.e. Paypal, Master, Visa etc. and provide related information to finish the wizard installation sequence, because of this, until today my Power Store 3 installation is unsuccessful.

My question:

Will it be possible to skip the request of any credit card related requirement, to install the product?.
Reading Power Store 3 feature; to my understanding one of Power Store 3 feature enable us to offer "product list", "add to cart" etc. doing "indirect online transaction", using email as communication with prospect customer/s, receive payment by check or money order.
We need to do this because our products need further to be discussed, negotiated, prepared and ship.

Can you help me to achieve the above objective?.

I am looking forward to hear from you through my email address mwbsc@canby.com or call me if necessary.
