File with a lock symbol on it?


Ok so I downloaded java jre1.6.0_32, and on the file there is a lock symbol on it. What does that mean? And when i try to make the file executable an error pops up and says

 "chmod: changing permissions of 'jre1.6.0_32':Operation not permitted"
How can i fix this?
 Thank you

You need to have admin priviledges , generally on command line, we do "su" and provide admin password to do such operation.

If that still doesn't work, you can try "su -" and see if that works.  I never understood why but some distros need the dash on the end.  Someone explained it once but I never understood the reason. 

:D :D
