I have no clue on where CodeByter/Carl Danley went, but seeing the github page he's quite active there, just not on DC for quite some time. And his personal page just throws a 404 at me :huh:
uncompressing the rar to WishList directory in your program files (x86).

You'd better
not install it there, a separate directory outside of any protected system folder, is preferred (and sometimes even required) for any portable software. Often used is a directory named Portable in your data partition (D:\Portable for instance, so for WishList it would be D:\Portable\WishList).
