Copying files from network drives to client.

Hi,
I am trying to copy dll files from a network drive to client machines for my appl.  I first unregister the local copies, copy the files, then register them.  It was easier for the users for me to use code than to have then run an install.

The following code works with clients running xp, but not win98 (statement hangs):

   Dim fso As new FileSystemObject
   fso.CopyFolder "J:\MyApp\*", "C:\Program Files\", True

I also tried filecopy but I got err code 70, "Access denied" on both xp and win98 clients.

   Dim fso As new FileSystemObject
   fso.CopyFile "J:\MyApp\DLLa", "C:\Program Files\MyApp\DLLa", True

Any help would be appreciated.

Thanks.
Mike
