Installation

I am getting an error while installing XP Emb. In the
database engine setup (I want all components on my PC), I
get the message
"Error reading from file C:\Program Files\Microsoft SQL
Server\80\Tools\Binn\sqlredis.exe. Verify that the file
exists and that you can access it."

Im logged on as admin. If I go to that directory, there
is a 0 byte file there with that name. If I abort the
installation, that file and directory is auto erased. Any
help?
Thx
