Microsoft Web Platform Installer 3.0 for Wordpress download

I've found an article online directing towards Microsoft Web Platform Installer 3.0. I downloaded and everything seemed like to it was going to be a breeze, and then trouble strikes. Darn I was so close!

I'd be grateful for any input. Here is where it goes south;

(Quick Note: I initially thought I installed it successfully, on the install screen the green bar was full, and it said download complete but it seemed to be frozen (I waited an hour with this screen, so I canceled it(a mistake in hindsight lol), and now when I try to download it again here is what happens:

1) After I press accept to install wordpress, it looks like it is about to install (goes to install screen) but then it goes to "enter application information" and wants me to choose (via drop down box) between creating a new database or use an existing one.

2) Next is database administrator, and there is already the name "root" in the box (which it allows me to edit).

3) Then it asks for database administrator password.

4) Then Database user name, which is currently set as: "wordpressuser"

...and then enter password and confirm password box.

5) Database server- which says "localhost" and finally Database Name which says "wordpress"

..and then the option for the unique key passphrases.

Grateful for any and all input!
