My CF10 is acting weird

So I got CF10 installed on my server next to xampp, when I launch the installer and get to this screen:

http://puu.sh/1uAB4

Then when I click "ADD" and go to xampp conf folder etc. I get this message:

http://puu.sh/1uADv

And then click OK, I get the next error message:

http://puu.sh/1uAEI

Is there any way to resolve this problem, or maybe the download link to Coldfusion 8?

Kind regards,
