Hi seskanda ,
I have really tried to find the file(s) you wanted, but without success.
The current versions file name is Shapeshifter.exe. Version 2.16 as you wrote. There are other programs with the same filename, but none of them have been your shapeshifter.
The current version is for Vista or higher. I guess that the company has changed the file name and that the the earlier versions have other names. It is pretty common that the companies do that when they release new versions.
Do you have a clue about what an earlier file name can be?
I am really sorry that I failed to find your file. I will probably try to find the file(s) and use other search words, but I have no time just now.
