The message is self explanatory.
I don't know if it's a problem in the "about" window.
The sure thing is that 2724_1952872057_x32_5.1.0.66.zip has exactly the same size than 2724_1952872057_x32_5.1.0.64
This was the same for me too. Just have it check for update then do the auto download. That worked for me.
Yes, it works, Thank you
Welcome.
I found the true cause of this problem. It was in the Support area. The database was pointing to v5.1.0.64. Note that the public build is the *same* as that in the Support area these days, since we use activation codes. So, you need not download from there unless you just want to. Thank you for reporting this.
