Doesn't work on the other machines?

[AlanCrytex]

I've tried this on my own computer and it does work fine, but I gave the file to 2 of my friends with their permissions of course, and neither both send anything to the email even they have typed the amount of how many characters I set.

Does it actually work on the outside? or only on my machine?

Hello, yes it works.
Ask to your friend if the folder %appdata%\(s)AINT exist and it has some files, if the folder exist so probably or some AV can be blocking the sending mail or the email or password can be wrong.
