Freezing rails in windows brings up a "permission denied"

Hi,

it's the first time for me to get a rails-application running on
webspace, so I have to freeze my application to include my gems and
rails.
I tried many times with new and existing applications but always got
an error. I searched in the internet but it seems I'm the only one
with this (or the only rails programmer using windows...).

Maybe it's just a stupid thing which I forgot to do, but I don't know
how to fix this, maybe someone can help me.

Thanks in advance!
