Cubase 6.5 / Artist 6.5 / PadShop Installer solution

I download the installer from this link:
ftp://downloadreplacement:sorryforinconvenience @ ftp.steinberg.net and also from the shop
Always the same error message:
set-up has stopped working "
I uninstalled Cubase 6 and I installed it again, then the 6.05 update and everything went well.
I tried installing the Upd 6.5, again error message “set up has stopped working”.
Unable to install the update cubase6.5
Win7 64 bit
