Unable to install paypal pro plugin into Payment Form (PMF)

I have just purchased paypal pro payment plugin for Payment Form (PMF) and i am unable to install it.

I went to Payment From -> Payment Plugins to install and it doesn't work. I get an error message each time.

Hello

From the screenshot, look like you are using a very outdated version of Payment Form and I believe that's the reason causing the error (that very old version of Payment Form is not compatible with the Joomla version you are using)

Please purchase and update your site to latest version of Payment Form. After that, everything will work as expected

BTW, please see eventbookingdoc.joomservices.com/faqs/paypal-vs-paypal-pro to understand the difference between PayPal and PayPal Pro and make sure you can use PayPal Pro before purchasing and updating to latest version of Payment Form
