Having an issue starting up Zandronum

[PrestigiousK]

So I've just now gotten Zandronum and I was trying to launch the Zandronum.exe file. It asks me to choose my Doom directory and I choose it but every time I do it the screen pops back up again asking me to choose the doom directory. Not sure what's going on here, and I've tried googling it and nobody seems to have the same problem I'm having.

With Doom directory, Zandronum means the directory that contains your IWAD files. Did you point it to a directory that has at least one IWAD in it?
