"Unable to connect to database with these settings"

I went through and found a bunch of posts having the same issues...however they were running linux. 

Right now I'm trying to test it on localhost using xampp using my windows pc. 

What do I need to do if I keep getting that same error every time I try to install elgg?

Do I just need to partition my drive and dedicate part of it to linux?

Or is there a way to install it on windows pcs/servers?
