I've installed Anahita successfully on Windows 8.1. I just have a small bug. When loading a page a get the following error:
Notice: Use of undefined constant JPATH_XMLRPC - assumed 'JPATH_XMLRPC' in C:\wamp\www\anahita-workspace\birth4\vendor\joomla\libraries\joomla\application\helper.php on line 68
Not sure why its only affecting me. Might be my error settings. None the less, it looks like that constant has been removed and it looks like that's the only place its removed. I thought all the RPC stuff was removed awhile ago so it should be safe to remove.
Commiting out those for lines seems to fix the issue and I haven't seen any other bugs.
Thanks for another great release!
