Parse error: syntax error, unexpected $end in install.php

Trying to install WordPress on my hosted server.
I’ve uploaded WP files to my hosted server into my_domain_name\wwwroot\blog\ directory. In browser, I go to my_domain_name/blog/wp-admin/install.php and get Parse error: syntax error, unexpected $end in C:\….my_domain_name\wwwroot\blog\wp-admin\install.php on line 82. Lines 81 through 83 are

$blog_public = 1;
	if ( ! empty( $_POST ) )
		$blog_public = isset( $_POST['blog_public'] );

within function display_setup_form.
The CP shows blog directory permissions as read,write,delete for my_domain_name and network services.
