admin/language/en-gb/extension/module/onwebchat.php → "opencart folder"/admin/language/"language you are using"/extension/module/
admin/view/template/extension/module/onwebchat.tpl → "opencart folder"/admin/view/template/extension/module/

catalog/controller/extension/module/onwebchat.php → "opencart folder"/catalog/controller/extension/module/
catalog/view/theme/default/template/extension/module/onwebchat.tpl → "opencart folder"/catalog/view/theme/"theme you are using"/template/extension/module/
catalog/language/en-gb/extension/module/onwebchat.php → "opencart folder"/catalog/language/extension/module/

Step 2 From the OpenCart admin panel, go to Extensions → Extensions, select Modules from the dropdown. Find onWebChat - Live Chat and click the Install icon. Click the Edit icon to configure the module with your Chat ID and Save.
