Arduino cannot run because it could not create a folder to store your settings

Hello,
I'm a teacher and I want to use ARDUINO 1.0 with my students. I can run it under windows seven with administrator account and it works fine. But the student can't have such an account and Arduino is not working. They get the following message : "Arduino cannot run because it could not create a folder to store your settings"
Does anybody have a solution ?

Thank you

One of two things is likely happening - Either your students will need WRITE access to the USER_NAME\APPDATA\ROAMING folder to create the appdata\roaming\arduino\preferences.txt file or they need WRITE access to wherever their USER PROFILE is being stored so that Arduino can write to the sketchbook location.

One possible workaround is to add the following line (without the quotes) to the preferences.txt file "settings.path=c:\Users*User*\WHEREVER THE USER PROFILE IS LOCATED"

Thank you for your answer ! I'll try this and will let you know soon.

Greetings,
Seb
