Hi gurus !

Just a question from a newbie. Trying to step on the tracks of Symbian developer. Downloaded SDK 2.1 for series 60. After installation on WinXP Pro can not start any of the applications. I have an error message: "Error attempting to read key"HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\1.4.1\JavaHome"
What do I have to do else? I have reinstalled just in case a new java machine from Sun: j2re-1_4_02-windows-i586-i.exe

And something more. What is the best start for such a dummy as me :-))
