Hey Alwin, after the update today, my Arma seems to be running pretty well. I will tell you if I encounter any issues. Thanks for your help all along the way! I really appreciate it.

so I entered the code and checked the profiling build- what do I do with the files I downloaded in the google docs? and what server do I join and how?

I played the game, this time in the Eden Editor. The error popped up again after 30-40 mins.

Oh yeah, I created a new profile by the way.

Alwin, I changed the profile parameters in the launcher to the location inside steam, C:\Program Files (x86)\Steam\steamapps\common\Arma 3\Profiles\Users

Ok. I will try to create a new profile. I don't really mind my singleplayer progress anymore(I won't transfer them), as long as my problem is fixed. I will tell you how it goes. Thanks

Well here are my specs:
I7 6700k
gtx 1080
hyperx savage ddr4 2400mhz

I reinstalled Arma, but the error persists.
f*ck

If I do reinstall the game, is there a way to preserve my singleplayer progress?
Note: I have Arma in the same hard-drive as my OS. Does that matter?
Note2: I played MP in a server for 20 mins, and Arma Crashed as well, same error.

should I just reinstall the game? i repaired files and Arma still crashes. I remembered to restart the computer.

When you say uninstall the tool do you mean deleting the app ?

Nevermind. Can I keep the tool? Do I have to uninstall it after restarting?

I am getting multiple results for the app. Do you have a link that I can use to download and install it?

Hey alwin. sorry for the late reply, I was out for winter holiday and was not able to access my desktop PC. I visited your linked page, and it says Directx12(latest one) does not have a standalone package for me to download. I have downloaded the latest windows 10 update, and the error is still there.

@Alwin, I have reinstalled c++ 2013, changed the memory allocator(you meant the launch options right?). I played the game again for about an hour, and the error popped up again. I am going to try reinstalling DirectX. Do you know how to do that? I need help. Thanks for your previous reply.

Allright. I will do these steps. I will reply if the problem persists or if it gets fixed. Thanks!

By the way, I have verified the game cache, updated my GPU and CPU drivers, updated my operating system, and changed the steam "Launch Options" to "-malloc=system ", still not working
