Hey Tony,
Thanks for reaching out!
Yeah, it is possible to do a manual install, I just wanted to recommend you to try it.
Download the plugins from your account.
Unzip them on your PC. You should have 2 folders, ‘event-tickets’ and ‘event-tickets-plus’.
Go to your file manager and navigate to wp-content/plugins
Completely delete the folders ‘event-tickets’ and ‘event-tickets-plus’.
Upload these 2 folders from your PC.
Go to your WP dashboard > Plugins, and activate them.
Let me know how that works out.
Cheers,
Andras
