Since Build 600 and Higher (17.02.2014):

1. MT4 has been 64 bit.
2. that was only used in off-line generators. No longer used in the Period Convertor.
3. the format of history has changed.

Are you trying to compile some ancient generator?

[Alain Verleyen]

MT4 is 32 bits application, and has always been.

[Mladen Rakic]

MT4 was never 64 bit

No problem with it (if you enabled dll imports in the indicator/expert/script options)

PS:  your PostMessageW() prototype is wrong
