The file 'devices.xml' containing the device SDK configuration could not be found

Hello,

I've installed SDK 1.1. I want to create some simple application for Symbian S60 3rd FP1, but I don't have anything in SDK S60 tab, and I get "The file 'devices.xml' containing the device SDK configuration could not be found looking at the registry key HKEY_LOCAL_MACHINE\Software\Symbian\EPOC SDKs\CommonPath or the common program data directories." error. What should I install to create apps for that OS? I've can only choose between Symbian^1 and Symbian^3.

thanks in advance
best regards
Tomasz
