Runtime 70: permission denied! [RESOLVED]

I make a few skins for MSN Messenger, but i thought i would try make a little program to install them without having to do it all manually. But when i get to the stage where it deletes the current msnmsgr.exe and copying the new one to its place. its says permission denied.
but the funny thing is, i can delete and copy things out of this program, but i cant do the exact thing via code? any help?
here is the code im using:

VB Code:

Kill ("" & msnpath & "\msnmsgr.exe")
FileCopy "" & txtpath.Text & "", "" & msnpath & "\msnmsgr.exe"

Is it possible that the exe is running while you're trying to delete it?

ah, may have something to do with it. (forgot to close it form the systray)

One of us is probably confused. It looks to me that what you are trying to do is to
1) Delete msnmsgr.exe, and then
2) Copy a file (the name is in the textbox) and name it msnmsgr.exe

If that's the case then after deleting the file you don't want to FileCopy, you just want to use the Name command (eg Name xxx.exe As yyy.exe).

well its working now anyway. im using the filecopy because i want to keep the original copy in its directory aswell as moving it to the msn directory and renameing it.
thanks anyway
