Clicking on the link to proceed brings me back to the same page!!

I am running Windows 2003 with IIS 6.0.

Can anyone help me out?

Thanks!

Upgrading to 4.4.1 gives the following error:

I've tried several times already so I'm pretty sure all the files are copying over.

I am extracting them from the Zip file downloaded from source forge. 

If you have a list of the files that are possibly missing, I can verify that they are copied.
