Am I just stupid?

[Shoxer]

I can't find includes/functions_showthread.php when I tried to install.
Can someone help please? :)

Thank you.

Sorry... I just found out I opened the 3.0.x installation when I need 3.5. My bad.

You don't need to do any file edits at all with 3.5.4, just upload the files, import the product (located in the includes/xml folder) and do the navbar and postbit edit.
