Nice one, abu afa.
FYI...you can download the app and get the serial number even if you don't install it immediately. Under powershadow (or Returnil) I went thru the installer steps, clicked on the "Get Serial" box, and the product key and serial numbers were sent to my email addrs. Then cancelled the install. I intend to install it on a computer that is not here right now, so no violation of the eula.
Used powershadow 'cause I was afraid it would do a full install before asking for registration, but it didn't.
Well, OK, probably everyone in the universe knew this, but there may be someone out there who didn't, so there it is.
