Getting Error Msg HELP!

[Mishqa]

I don't know what to do I tried installing SimpleDesk and when I do I get this msg:

You cannot download or install new packages because the Packages directory or one of the files in it are not writable!

What can I do? And pleas explain things to me as I am farily new to SMF.

This isn't actually a bug limited to SimpleDesk, this is a much larger problem that will affect your ability to install any mods of any kind for SMF.

Have a search on simplemachines.org, you'll find it covered many times, including what to change to make it work on your server.
