I have a Windows 8 laptop (64-BIT intel CPU); that I run Bitshares X on. I downloaded and installed the 64-bit version of 4.12 BitsharesX but when I ran it, it would not work. It gave me an error that I did not understand. After that I uninstalled the 64-bit version of Bitshares X 4.12, I downloaded and installed the 32-bit version of Bitshares X. After installation was completed, I ran the 32-bit version and it worked. At this point, it is reindexing (31% complete as of this post). It seems that the 32-bit version of BTSX 4.12 wallet for a Win8 computer works and the 64-bit version does not work. That was the situation for me.
