not launching after update 9.9.GJ26
Game not launching after Update (9.9.GJ26)
not launching after update 9.9.GJ26 (but everything was fine all the months and years before)
While the game was working fine for many years now, today I have the first update getting me stuck totally.
I have old version of mtga, and double checked BEFORE this update, the game starts, and requesting new version.
->MTGA Launcher.exe doesnt install the update properly. (I dont know the error massage; something was corrupt).
It said it wants to install something and requesting windows to reboot for it; but shortly after, the install of the update aborts unexpected, and doesnt finish the process.
I rebooted my PC, and ...
Then when starting MTGA.exe it gives me a error code 0xc0000005 upon launching.
Then I looked the install directory, and I did find the new update (31 mb) in the update folder.
I started it manually.
The installation took some minutes, succesful.
Now, When I launch MTGA.exe or MTGAlauncher, it will load as a process with 200 kb, and nothing happens.
I can start multiple instances of this process, but its doing nothing.
The game was working fine to this day on my Windows 7 legacy update. Newer games work fine with VXkex API extension.
I didnt use VXkex for MTGA yet.
Before I elaborate this, I want to know, If a usual update can fix my problem?
As I said, all the time its running fine.

I have seen other issues, But I dont know if its down to the same origin.
(posted by Kazu in language I cannot read).___
I want to UPDATE this Subject, because I have now 16.9 = 1 week later come to update my VX Kex API Extension to Version 1.2.1.2229 vom 21.Juli 2026,which I now start to use on Win7 to continue playing MTGA after 1 week of being unable to.
Which was working WITHOUT the addition, and for non-experienced users, I suggest anyways to solve the bug at its origin.TLDR: With the new version of VXkex I am 100% able to launch the game on the same PC and I can play without relying on a Updated version of MTGA.
So This is RIGHT NOW a SOLUTION AKA WORKAROUND.
But if you dont pay attention, then a future version of MTGA can break the compatibility once again at any time. I will report about it. I hope I never need though. -

ウィザーズオブザコースト のサポートに伝えているんだが、全然情報更新しないわ。
Unity6 に対応できる環境にできるならしてみたらいい。ーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーー
Unity6 へのアップグレードにより、公式の推奨環境や動作最小環境の情報と Unity6がインストールできる環境が違うようすなのでUnity6の環境を満たせるなら試してみてもいいかも。ーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーー

I try to reinstall MTGA ( I deleted the folder, but kept "MTGA_DATA"...
MTGAinstall, runs into MTGA_Launcher, both works through, and then downloads "MTGA.exe", and upon launching that one (freshly downloaded AND validated), it instantly run into "Error 0xC0000005" (see .png file) which references on corrupted files something;
