just upgrade to latest XAMPP with PHP 7

Enter "InnoDB: Error: unable to create temporary file; errno: 0" into Google and follow advices. There are different reasons for that error.

I fixed the problem by creating folder for tmpdir.
It wasn't created. I suggest checking existence and permissions/security.
