Xampp Install Issue

I am doing a fresh install with an older version of Cs Cart Multi vendor version 3.0 on a fresh install of Xampp 7.0.6 , I am getting the following error

Warning: session_start(): Session callback expects true/false return value in C:\xampp\htdocs\cscart\core\classes\session.php on line 277

Fatal error: session_start(): Failed to initialize storage module: user (path: C:\xampp\tmp) in C:\xampp\htdocs\cscart\core\classes\session.php on line 277

I have confirmed that the cscart tables exist in phpmyadmin. I get the same error in all browsers.

Make sure your php version is supported by your cs-cart 3.0 version.

That appeared to be it, I hope my hosting provider doesn't upgrade their PHP!
