[Camino] I cannot download updates.

Hello,

Thanks in advance for your help!

I have a 12" Mac G4 powerbook 1.5.

I am new to Mac's and am in need of some help please.

Also I am no computer wiz.

When I try to install the Camino update my Mac says:

"Camino does not have permission 
to write to the application's directory!  Are you running off a disk image?
If not ask your system administrator for help."


I have no idea what this means.  I have been able to download various Mac  and Adobe updates.

Any help would be greatly appreciated!

Thanks,

Paul D.Cooper
