I found way to do it.
Start multiple instances of x3 tc, when you get first error, dont click ok.
Go to task manager, and check if there is x3 tc exe with 45.616 memory allocated, close all others, that one with 45616 will run.
I just run it 3 times this way.
other two memory numbers were 45592 and 45588 and neither of this wouldnt run.
enjoy
works with 45624 too.
Update its easier to run it with loaded cpus, i usually do blender render.
deal is to load cpu then run exe.
