I have just re-downloaded the Ver 3.12 Build 26773 and I can assure that is identical to the one I downloaded of Version 3.12 Build 26729. is byte identical. I have several programmes that can doi this and they all give the same result.. No-one has yet addressed this very real issue. Unless the setup programme now downloads the its that changed from that Version from an online source. I have not run this new programme but keep a history of all the various releases. I am not just talking that the Version 3.12 build 26773 executable has the Version 3.12 Build 26729 stamp on it but that is is very much identical byte by byte to the Build stated above. ?

Can't see what is happening. I can download new versions of every other software that uses the same link and get new Versions. This has only been happening with uTorrent since Build 26729.
