Hello,
The menu is generated by HikaShop during the installation.
If the menu is not there ; it means that the installation did not finish completely.
You can install HikaShop 3.4.0 again and it will perform some verifications of your database integrity and it will also re-install the menu.

By the way, do not send me private message, use the "contact us" form instead.
