Dear friends:

I need to change the ownership of a file in order to run it. I've 
already installed it by su-ing to root in the console. It installed in 
/usr/local but in order to run the application executable I need to 
change the ownship (which is currently "root"). Actually, I am little 
confused. I tried to run it in the console by su-ing but failed. What am 
I doing wrong, please?

By the way, all of my devices installed perfectly, including my printer. 
So I am really delighted. SL detected everything perfectly.

Thank you.

Benjamin
