Visual Basic - Error 76. Error de acceso a ruta

Muy buenas les cuento mi problema. Estoy intentando copiar un archivo dll que tengo en la carpeta de mi programa al system 32. La cosa es que cuando lo intento me sale ese error y no consigo solucionarlo. El codigo empleado es el siguiente:

MiArchivo = App.Path & "MSDBRPTR.DLL"
FileCopy MiArchivo, "C:WindowsSystem32"

He probado a copiarlo en otra carpeta cualquiera por si no me dejara por ser system32 pero aun asi no hay manera. El archivo no esta marcado como solo lectura ni nada por el estilo.
A ver si alguien sabe como solucionar esto pq no lo entiendo, muchas gracias

Parece que tienes un problema con el FileCopy, te propongo otra solución:

--- código:
Dim FSO As New FileSystemObject
Dim File As File
Set File = FSO.GetFile(App.Path & "\MSDBRPTR.DLL")
File.Copy ("C:\Windows\System32\MSDBRPTR.DLL")
--- fin del código:

Tienes que marcar la referencia a Microsoft Scripting Runtime

A continuación, como te indiqué antes, tienes que registrar la librería, sino no vale de nada.

Y si te funciona, espero que lo indiques y si no también!

Ahora parece que si copia bien, ya que al hacerlo a una carpeta de destino de prueba lo hace sin problema, sin embargo al intentar hacerlo a system32 me da error, permiso denegado...
A ver si esto se puede solucionar.

Revisa las propiedades del directorio System32, es posible que sea de solo lectura, oculto o esté protegido.

Bueno el problema venia porque la Dll que queria mover la usaba el propio VB, asi que fue crear el .exe y al cerrar el vb ya me dejaba....

La cosa es q ahora tengo otra duda, respecto a un tema de imprimir que comente en un hilo anterior, aver al hacer click en el boton de imprimir llamo a un modulo .bas el cual contiene el siguiente codigo:

Como veis he metido la orden printreport del reporte al final de haber elegido la impresora, la pregunta es, esta bien colocado en esa posicion? En mi casa funciona pero donde lo tengo q ejecutar no...
Muchas gracias
