Migrating from linux to windows, path errors?

I recently installed wp 4.3.1 in a linux shared hosting environment. I am attempting to migrate it to a windows 2012 shared hosting environment. I restored the database (mysql) and altered the db name, server name, user name, and password in the wp-config.php file. When I attempt to launch the site I get the errors below. The errors mention the settings file, I didn’t mod that and expect I don’t need to. Is for example line 21 the first non-rem’d line, and not strict line count? It’s not a multisite installation or anything complex like that. I would appreciate help with this issue.
