When the download is complete and I double-click on the icon I get an error message telling me the set-up files are corrupted and to obtain a new copy of the program. I have spent quite a lot of time checking the message archives but I can't find a solution. If anyone else has one I would really appreciate it if you could let me know.

I guess an error with a proxy, since the file on UK's CRAN mirror is fine.

a) Try to get a version from another mirror (CRAN master already has 
R-1.9.1 which you should install rather than the outdated versions 
mentioned above)

b) Try to bypass your proxy.

c) Your system might be corrupted, if this happens for other versions 
from other mirrors as well.
