I had the same problems with the installer on Windows XP and Windows 7. I do the same as totalbeginner. There are instructions on the Aware websit somewhere telling you what to do. I think you download the updates as a .zip, expand them on your PC and copy the contents to the SD card, which you need to stick in your PC. There always seem to be 2 .zip files to download, and I am never sure which one I need so I just do both. Always seems to work for me.
