I get a error-dialog box.
If i click "details", it says it want to copy
to some weird filename, starting with driveletter "@".
I tried it on 2 different machines, and tried 3 different
ftp sites to get the program from, because i thought 
there was some bit wrong in the file on the ftp server.
i also tried unpacking it with pkunzip, that worked fine.

i think the main install-file is corrupted.
