Template.PNPROJ Help??

Im taking the hello world tutorial

[wiibrew.org]

And Its really confusing to me..

I have a folder on the c: drive called Projects/wii

I Copied the folder C:\devkitPro\examples\wii\template\

And I made it so that the full path is c:\projects\wii\helloworld\

So I open the programmers notepad and I am lost...

The tut says:

Compile the Hello World Example

* Assuming you installed Programmer's Notepad through the installer, double click the .pnproj file in your new project.
* Click on Tools->make or use the ALT+1 key combination
* The output window at the bottom will show the build progress

Note: If you are having trouble compiling some programs under Windows Vista (eg. libogc cvs), try unsetting PLATFORM variable. (in msys shell, "unset PLATFORM")

^^^^I am running Vista 64bit and I have no idea how to do this....

Anyway It says open the pn and doubleclick the .pnproj file in my new project..
So I have a new window. But no .pnproj
Do I write Hello World into the notepad maybe then save it as Helloworld.pnproj
Then compile it??

What about unsetting the platform variable??
How is that done or should I worry about it??

Thanks for any help and putting up with me
Im a total newb

Inside the Hello World folder you should see a source folder, Makefile and template.pnproj. Double click template.pnproj from an explorer window, PN2 should open and load the project. You may only see "template" if the extension is hidden, I'm not sure offhand.

Where you're getting confused is by opening the editor first.

As for the PLATFORM variable, it's not something you need to worry about.
