Trouble with the 017 Arduino EXE File

Im a Newbie - and putting just the Arduino Duemilanova with a Mega 328 via Usb (will be com 7) to the WIN xp(SP2) computer;
Starting the Arduino exe file and got all the time the following Error Message:
Could not read color theme settings - you will need to reinstall processing.
The IDE programm does not start.
Trying this on 3 different computers.
2. in the 80 MB file (arduino 0017) from the Arduino Page
there are NO!! drivers included. The folder is empty !! Also the example Folder is empty.
Is there anybody who could help to solve the problem with the ERROR Message above ??

I SOLVE THE Problem !!

The reason was the UNZIPP Program called IZARC
This IZARc program does not unzipp all the parts of the 0017 Arduino Zipfile.
But with the WIN ZIP TOOL all works very well.
