Question about the 6.2.3 client offline

Hello dear people,

There is no possibility of a 6.2 3 or 6.2.4 as Lan wants to start full client offline Party play but the client always says no internet connection when I start.

It should give a patcher.exe that is possible but it is not synonymous. I have tested many. I move the Wow.exe In the patcher.exe nothing starts and again the same.

I want to play 6.2.3 or 6.2.4 offline without internet connection.

Could one say how that is possible.

Just wondering since trinitycore only supports 3.3.5a and 7.2.5 why would you want 6.2.4 when you can get the other ones or even the higher one after that or even 4.3.4
