CC-MODE not working from different user

I am running eMacs from another's users directory: ~sbuesr/emacs
but I can't get the CC-MODE or any other packages to work. If I work from that users' account, it's ok. If I use my account and run emacs, it's not working.

Any ideas please?

check your PATH and LD_LIBRARY_PATH variable make
sure you've included the path of the CC-Mode
program.

finally check your permission.

Thanks for your answer.
But what permisions I need? 777?

if the problem is a permission problem then 777
will do the trick but it is not adviseable to give
777 permission to a program due to security reason
you only really need a permission that allow you to do what you need.

try different permission and see which one works
depend on your group.

Give yourself the same permission as the other user or simply run the program as a root user
