By saying we can't decompile or reverse engineer the executable is very suspicious because then you can't tell if it's a virus yourself. Also, you don't have any safeguards in place so nobody can extract it. I just used 7-zip to extract it no problem. You could at least make the executable have a password to extract it. Your licence.rtf file doesn't even have text in it. No terms or conditions either other than "if you download this you cannot do anything to make sure it's not a virus". I'm not trying to hurt anyone's feelings I'm just letting you know that there are some major issues that need to be worked out.

I'm not saying it's malicious, I'm saying that there needs to be at least a password to the exe, an actual license file as well as other issues that need to be worked out as well. I get it's closed-source but doesn't mean that there's anything stopping someone from extracting it and/or making a malicious copy of it.
