I've downloaded and installed the 64-bit version of Windows 7 and using it to do some 64bit programming and include adjustments, everything's working good so far except the MOVZX intruction, which gives me an error no matter what registers and size specifications I use. I've tried some of the suggestions in the intel docs but this hasn't worked. Maybe a bug? Confused

All of them work for me.

Code:
use64

movzx eax, al
movzx eax, ax

movzx rax, al
movzx rax, ax
    


MOVZX RAX, ECX doesn't exist because MOV EAX, ECX makes the same job.

[EDIT] Embarassed
Sorry, my fault, I was doing things backwards.
something like:
local qalign:QWORD
movzx al, [qalign]
they work good when you use them the right way! Rolling Eyes
