problems with running arduino

Development Tools IDE 1.x
1

Hallo,
I want to run the arduino software in our school network but it doesn't start (clients Win7). The reason seems to be that arduino.exe tries to write a file or folder but has no permission. Trying with arduino19 the message "Arduino cannot run because it could not create a folder to store your settings" comes, trying Version1.0.5 nothing happens at all.

My Question is: What directory is the software trying to write to and how can I change this?

File:Preferences, is likely trying to create a sketchbook folder.

I have found the solution:
Arduino.exe ist trying to write folders in the directory that is marked in registry in the key
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\AppData

In my case the value of this key wasn't correct(no write permission) so I changed to another value.
