Yes, unless you specify /LARGEADDRESSAWARE:NO ...

Strange... Live and learn, I guess... thanks for the link.

lea rcx, hInstance

Just tested. Instruction

--- Code: ---lea rcx, hInstance

--- End code ---
also is cause of linker's clause, "Relocation type ADDR32 is invalid without /LARGEADDRESSAWARE:NO, for symbol...".
May be I should write some another form of this instruction? Or I can change other linker's parameters?
What is interesting: I wrote the same "hello world" application by C and read disassembly. There is another string and no linker clause:

--- Code: ---lea rcx, [hInstance]

--- End code ---
Square brackets added. But in assembler file clause presents, at both variants, with brackets and without them.

Greenhorn:
Maybe it is more helpful if you could post the whole ASM code and the console output ...
Or better attach the whole project files.

This comes daily in my mind, too...  :D
