WiX definitely supports x64! I got the same issue and that seems to be somehow a crazy issue as I also got it working for another solution for x86 and x64. So I compared the two solution files and figured out what was going wrong with the one not working.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
