Detect if your Windows version is 32- or 64-bit

[Raistlin]

HEY I am all for learning  :t There's just a small
problem with the detection logic, which I wont
share here. PM me please when you have time.

I already pm you Raistlin  :icon14:...but why you don't want to share the error? is a security critical thing?  :shock:

[Raistlin]

No nothing serious  ;) PM'ed you back .... no security issues - don't worry.

is a security critical thing?  :shock:

Take care Felipe  :icon_eek:

Erm...I am not quite so nefarious.
But thanks for the thought. I have
supplied Felipe with the required
thought processes. Its up to him
to decide to share his outcomes.
No conspiracy theories required  :t

Well the issue in the 64 bit app was that if this app runs in a 32 bit system it will crash...  :exclaim:

Hi jj2007,

Nice work there.

My version is similar to what fearless pointed out

Code Select Expand


MOV DX, CS
.if DL == 1Bh
      ;32Bit System
.elseif DL == 23h
      ;64Bit System (WoW)
.else
      ;33h value for 64Bit Native (Exe + System)
.endif
