problems with proxy

[Miriam Wolters]

Dear Sir or Madame,

I got a problem with installing KDE for windows 7 (64 bit).
The latest installation file does not work, it say "its not a prober 
win32 anwendung"
If i use an older version, it starts the installation process, but 
stops, when trying to download the mirror list.
It appears that the KDE Windows installer can't use a proxy at the 
moment - as it appears to fail downloading it's list of mirrors.
Is it a general problem? I'm not a computer specialist, i only want to 
run r and kde for rkwards for my statistics...
Thank you in advance, M. Wolters (Germany)
