Has anyone tried installing Web Reporter on a 2012 server? If so, how'd that work out? I can't imagine it wouldn't work, but you never know.
Server 2012 isn't on the officially supported list, so any issues related to the OS, for example service crashing, wouldn't be supported. But I would expect it to run fine if the installer doesn't complain.
I'll let you know soon enough. Give me a couple more weeks!
