Hello
I'm trying run the Exchange CU2 setup on a Windows 2012 server however every time I try I'm prompted with a message that says "The current mode or operation is not specified".
The server is litterally an out of the box install with the latest Windows updates - theres nothing else on there. I've even tried it on another Windows 2012 server and I get the same issue. If I run the install on my Windows 7 SP1 admin machine it works and the wizard appears. I can't seem to find anything on Google about this. Also, I am running the setup using an account with correct privileges etc. Any ideas?
