256 CPU I modify a little the exe I buy to adapt it

[fire4music]

I buy Ableton Live Suite and I have a 256 logical CPU system ... Ableton Live crash but I found where the bug was:
In a Hyper-V 128 CPU Ableton Live Suite is ok but in my system a PC with 2 x Epyc 7742, 1 Tb of RAM and 2 GPU Nvidia L40 the exe was crashing.
I found in the byte codes that 64 was tested and thrown an error when the exe is not in the Hyper-V.
It's ok that Ableton limit 64 as usable CPU but if with a 128 Cpu count the exe is ok, it must be ok also with 256 cpu count.
I think It's legal to modify an exe to make it work on a system where it cannot work without.
So I correct it like this:

00000001423AF22F 4C 8B C0 mov r8,rax
00000001423AF232 48 8D 55 C0 lea rdx,[rbp-40h]

I made it in both Ableton Live Suite and Ableton Index.
And now I have:

I set a reddit channel to explain what I test:

I hope that bug will be fixed in the V12 (I am registered to buy it ...).

Your best bet is to contact support with this, they won’t see it if you just post on the forums.

I have already sent requests with attached dmp.
I am writing here to point out that the problem exists but that it has a solution which is not trivial if you do not know how how to debug and correct a ".exe" or a ".dll".
Because it's rather frustrating to buy a powerful PC and find that one of your favorite software refuses to launch...
Furthermore, this is the first time that I have modified an Ableton binary and I would like to have your opinion on the simple fact that, even if I am certain that it is legal, how can Ableton react?
I buy all the most famous DAWs and I have no desire to have to modify them because I develop converters, gateways, so that creative people are not limited by technical problems.
