You may get better response if you post this on farcry-dev (
https://groups.google.com/forum/#!forum/farcry-dev). This is a forum more focused on the end users of FarCry. farcry-dev is for developers.
That said, what do you mean by admin console? Do you mean the FarCry webtop? You said you created a /farcry mapping, which I assume you mean in the CF Administrator. For FarCry 3.0 you also need to create a /farcry web server virtual directory in IIS pointing to /farcry/farcry_core/admin
If thats not the problem, are you getting any error messages or anything else that might help troubleshoot?
