Can't create variable of weigth more than 2 Gb

[Please_Help_me_D]

Hi all,
I encountered a problem that bothers me. I know that on x32 bit system a program that were compiled with x32 compilator can't include variable of weight more than 2 Gb.
But my system is Windows x64, MSVC x64 compilator and I use Qt Creator 4.10.1 that is based on Qt 5.13.1 compiled with MSVC x32.
If I run:

int data[2000][360000]; // 2.88 Gb

I get an error like:
C1126: automatic memory allocation exceeds 2G
Is that beacause my Qt is compiled with x32 compilator?

A 32-bit application cannot use more than 2 GB of memory, even if your operating system is 64-bit.

int data[2000][360000]; // 2.88 Gb

You cannot have 3 GB of data on your stack. Use the heap instead.
