Worldpay will not work on ver. 4.2, I can't use a plug in, needs to be redirect type method

Worldpay will not work on version 4.2, I can't use a plug in, needs to be redirect type method? My older .asp sites work fine, but just can't get this nopcommerce to work, I have all the older codings, poeple are trying for me but fail, so frustrating, all say, "I can do it" none can!!!

Have you asked the vendor if they will update their plugin:
https://www.nopcommerce.com/worldpay-uk-payment-gateway-plugin
?

My method is the redirect, business gateway version, not a plug in, they don't work

In nopCommerce, all Payment Methods are build as plugins.

there is a way as I'm not the only one with this method.

Have you asked the vendor if they will update their plugin:

?

no as plug ins don't work with the way i'm with the bank on redirect business gateway with an i.d. no.

I can use the Worldpay plug in for now that came with version 4.2 but i deleted it and can't upload it back on the site, called Payments.Manual, I think it is here, but I can't use RAR so what one is .zip and what one to download? https://github.com/nopSolutions/nopCommerce/releases/tag/release-4.20

Worldpay plugin is called Payments.Worldpay
Download the version from nopCommerce
https://www.nopcommerce.com/download-nopcommerce-link?type=nosourcepackage
Use https://www.7-zip.org/ to unpak the .rar file

I found Payments.Manual in the list when extracted?
