I previously had FMS 11 installed for testing and decided to give the newest version a whirl. It hasn't been pretty. This installer itself usually crashes without error before the installer window is even displayed. Once I'm though that and it's installed, Admin Console still won't launch. At all. It usually timesout with an HTTP Status 500 error. I've scoured all the documentation, and no one on the interwebs seems be encountering this issue with this version either.
OS X 10.7.4
Java SE 6 1.6.0_31-b04-425
As I said FileMaker Server 11 was working perfectly. I hope someone out there knows something more.
