XF 2.1 Errors on install

[Stan]

I am getting the following error after I enter my Sql details and click begin installation:

Server Error
count(): Parameter must be an array or an object that implements Countable

1. XenForo_Application::handlePhpError() in XenForo/Install/Model/Install.php at line 283
2. XenForo_Install_Model_Install->insertDefaultData() in XenForo/Install/Controller/Install.php at line 219

I have tried php 7.3 and 7.2

I think I got this one fixed, I grabbed 1.5 by mistake.
