Only the latest official build is supported (in DX11 mode), sorry.
Thanks for the quick reply! Would it be possible to also support the vanilla client in the future? Can I submit this as a feature request somewhere? :)
There is a quite active community of players e.g. on everlook.org which has 5-10k active players currently and I have seen some other people on this board here that tried to play vanilla too.
Cheers :)
I have the same problem and would be interested in a solution or a hint how to further troubleshoot this.
Vorpx does not attach to the vanilla wow client (v1.12.1).
It works just fine for the retail and the wowclassic client but not for the vanilla client that is used for most private servers running the real vanilla wow.
Cheers :)
