Due to a security "enhancement" by Microsoft for IIS, files to be downloaded may not end in .exe. The installer files are being renamed to .exe.bbb which bypasses the "security check" so remove the phony extension upon download. My apologies for the inconvenience but my company uses IIS for its web site.
On that note, a while ago someone mentioned that they would be willing to host the binaries for me. If that is still a possibility please contact me and I'll see what can be arranged. Thanks.
