installing price manager plug

Hi, I noticed on my download account. There are many plugs under pricing manager. Do I need to install all of these?
Pricing Manager
geodir_payment_manager
geodir_payment_manager_v2
wpinv-payfast-payment
wpinv-sagepay-payment
wpinv-stripe-payment
wpinv-2co-payment
wpinv-affiliatewp

as a test, I installed only geodir_payment_manager_v2 and wpinv-stripe-payment, but once I activate wpinv-stripe-payment, the whole website no longer works. I receive this message when I open the website.

Fatal error: Uncaught Error: Call to undefined function wpinv_is_checkout() in /home1/rateaday/public_html/wp-content/plugins/wpinv-stripe-payment/includes/class-wpinv-stripe.php:153 Stack trace: #0 /home1/rateaday/public_html/wp-includes/class-wp-hook.php(298): WPInv_Stripe->enqueue_scripts(”) #1 /home1/rateaday/public_html/wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters(NULL, Array) #2 /home1/rateaday/public_html/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #3 /home1/rateaday/public_html/wp-includes/script-loader.php(1296): do_action(‘wp_enqueue_scri…’) #4 /home1/rateaday/public_html/wp-includes/class-wp-hook.php(298): wp_enqueue_scripts(”) #5 /home1/rateaday/public_html/wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters(NULL, Array) #6 /home1/rateaday/public_html/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #7 /home1/rateaday/public_html/wp-includes/general-template.php(2589): do_action(‘wp_head’) #8 /home1/rateaday/public_html/wp-content/themes/directory-starter/header.php(8) in /home1/rateaday/public_html/wp-content/plugins/wpinv-stripe-payment/includes/class-wpinv-stripe.php on line 153
