I'm having a problem installing ZEN7 SP1 IR4 on a NW 6.5 SP7 server. This is brand new server, ZEN has never been installed.

When I get to the screen where I select the server to install to, I can select it and click OK, (see screenshot) it takes me back to the "Server Selection" screen (where I should be able to click Next) but the server is not added to the list.

I'm logged in as an Admin equivalent user, I've tried logging in again, restarting my Windows workstations but the server won't show. Any ideas?

I've also tried to download the installer again but it seems it's not available now, any thoughts on this?
