end

Heres what i put to start it

WCE.Install()

And heres the error i get:

WCE:2: attempt to index ? (a nil value)

Please help!

Not a bug. Moved to Ask a Pro.

APIs do not have access to the shell "API", as they aren't programs. Try using os.run instead.

Or pass the shell API:

-- the API
function Install(shell)
    shell.run("rom/apis/win/install")
end

-- the program
WCE.Install(shell)

ok i will try that thanks also i have another problem

function del(file)
if fs.isDir("RecycleBin") then
else
fs.makeDir("RecycleBin")
end
if fs.exists(file) then
fs.copy(file,"RecycleBin/"..file)
fs.delete(file)
else
error("No Such File")
end
end

Its says Copy Failed

whats the problem with this code?

That's because the second argument given to fs.copy is the destination folder, not the full path of the new file. By the way, use fs.move. It's the same as copying and deleting something.
