Well odie,
I re-downloaded the package,and renamed the file to 'ufo-install.exe' ,and at the bottom saved as 'all files' for type of file,as this may have been the problem before.And...the files are finally being unpacked onto my hard drive! so far so good!
I am looking forward to this,as I am a huge fan of XCOM,have all the UFO games made by Altar,and am currently playing UFO Extra Terrestrials too.This looks really good.
I will keep you posted on my progress.
Thanks mate!
