We've checked the links and it all seems to be fine.
Can you please try downloading and saving to disk the stardrawcontrol.msi:
http://download.stardraw.com/downloads/control/english/rc2/stardrawcontrol.msi
If you have already installed .net 1.1, then the msi should not ask you to install it again.
Please let us know if you are able to download the msi or if it is still asking for 1.1 to be installed.
