A ham friend is having a problem with SATPC32. He didn't know what version he is running. His computer is running Vista and when he tries to load SATPC32, he gets a prompt that mentions a "64 bit" problem. Sorry to be so vague, but I'm getting this second hand. Has anyone had a problem that sounds similiar to this and if so, can you share any advice on how you solved it?

Thanks,
