What works

Playing itself works perfectly, as far as I can tell. However, many workarounds were needed to get there, and some glitches remain (see below).

The game installs with the official installer.

Then the game downloads many files.

The game connects to the game servers.

Deckbuilding, matchmaking, and playing - all work.

What does not

The installer displays several graphical glitches, making it essentially impossible to read anything. However if you've done the installation previously (e.g. on Windows), you can figure out to just click Next a lot, at the bottom. The early check box is "create a desktop icon?", which I declined. As far as I know there is no workaround for these graphical glitches.

When the game downloads files, for example right after the initial installation finishes, intermittently the program will crash, displaying a "gcThreadContext" error. This is apparently a known bug ( See below for a partial workaround to this.


In order for MtgaLauncher.exe to run, I had to install dotnet 4.7.2. This in itself is a process, which you can google for more details. But the basic procedure is:

- create a 32-bit wine prefix;

- uninstall mono from it;

- set windows version to XP;

- install .net 4.0 (download from Microsoft);

- set windows version to 7;

- set mscoree.dll to native in winecfg -> Libraries;

- install .net 4.7.2 (also download from Microsoft).

Alternatively, you can use the latest winetricks to install dotnet472 (download the latest winetricks from the winetricks github - it's just a single file: a huge shell script). But for me, doing it with winetricks took much longer, because it installs many more intermediate versions of dotnet.

To get around the gcThreadContext crash while downloading files, you can just restart the game when it happens, and it'll continue downloading where it left off. However, if you'd like to go do something else while it downloads, you can minimize how many times the crash occurs, by running like this:

WINEDEBUG=+relay,-debug wine MtgaLauncher
This makes the game run much slower, but it steadily makes progress downloading, and can do so unattended. Sometimes it still crashes, but it's much, much less. Once it finishes downloading, exit the game, and run normally, without WINEDEBUG=+relay,-debug.

In order to connect to the game servers, I needed another workaround, and this one I couldn't find with google. The game was giving an error: "Unable to connect. Could not establish connection to environment: An exception has occurred while attempting to connect. wss://" (the exact address may vary). To fix this, I had to turn on IPv6 in my Linux kernel.

Many thanks to DarkShadow4444 from FreeNode irc #winehq, who helped me produce and understand the wine debugging output, which helped me figure out that I had to turn on IPv6 in my kernel.

HowTo / Notes

How to get MtgaLauncher.exe to work
  1. Set up a 32-bit Wine prefix
  2. Set Windows version to Windows 7
  3. Install dotnet472 using winetricks

This should allow you to run the updater. 

Note that this does not fix the GetThreadContext failed bug.

How to fix game locking up when alt-tabbing

The alt-tabbing is fixed by adding a registry key for "HKEY_CURRENT_USER\Software\Wine\X11 Driver\UseTakeFocus" and set it to "N"

Fixing the "Fatal error in gc, GetThreadContext failed" crash when downloading game files

It is possible to overcome the "Fatal error in gc, GetThreadContext failed" crash when downloading game files by using a patched version of wine. (see the discussion here

For those using lutris there is a build with the patch enabled available called: tkg-mtga-x.xx

patched wine for Playonlinux
by Lluís Gili on Wednesday May 29th 2019, 14:47
to avoid "Fatal error in gc, GetThreadContext failed" while updating there's a little patch in
if you are using Playonlinux, you can download patched wine 4.9 here
put it in ~/.PlayOnLinux/wine/linux-x86/ and choose wine version 4.9_patched in Playonlinux, after update return to your previous wine version
MTGA Installer
by tagelicht on Sunday May 5th 2019, 14:11
For me using wine 4.7 (OS set to Windows 10) the installer works fine (though for some reason, only in a clean wineprefix). Its Graphics are terribly broken, but it installs the game. Updating doesn't work though, but I will try the workaround so I dont have to reinstall all the time.

The game works great, performance is flawless, and as described in the corresponding bug creating a string "UseTakeFocus" in "HKEY_CURRENT_USER\Software\Wine\X11 Drivers\" fixes the game not receiving input anymore after tabbing out.

Other than updating and the tabbing bug I did not notice any bugs, while playing the game intensively ;)

The latest installer seems to be broken with newer wine versions
by ZeroPointEnergy on Thursday March 28th 2019, 7:34
I tested with the following wine versions, every time with a new prefix:
- wine 4.1 (works)
- wine 4.2 (works)
- wine 4.3 (broken)
- wine 4.4 (broken)

Looks like the breakage is somewhere between wine 4.2 and 4.3. I did not test with staging wine so far.
RE: The latest installer seems to be broken with newer wine versions
by ZeroPointEnergy on Monday April 29th 2019, 10:04
Just for the record: There was a regression introduced in 4.3 that breaks the installer of MTGA. This was supposedly fixed in 4.5 (I did not test this version), but in 4.6 another regression was introduced when a staging patchset was merged upstream incomplete which is now again fixed with 4.7.

So if you have trouble installing, try a wine version =4.7
updater stopped working
by Lluís Gili on Wednesday February 20th 2019, 14:15
since last two updates I can't update and had to re-install from scratch
any workaround for updating instead or re-installing?
RE: updater stopped working
by Lluís Gili on Wednesday February 20th 2019, 14:36
found "wine uninstall" command, with it is quick enough to re-install, I was creating the whole wineprefix and re-installing dotnet
Lockup after alttab
by Anton Romanov on Thursday February 14th 2019, 23:45
That "stops accepting input after alt-tab" thing is better of fixed by adding a registry key for "HKEY_CURRENT_USER\Software\Wine\X11 Driver\UseTakeFocus" and set it to "N"

GC error workaround
by Doesn'tMatter on Tuesday October 9th 2018, 22:10
For me running game on one core only fixed the download assets issue (GC thread error). I needed to restart it couple of times anyway but I was able to download all in the end.

Try running lutris like this:
$ taskset --cpu-list 1 lutris
by Drew on Friday October 5th 2018, 21:55
Given the weird black box issue with the installer, is there a way to tell the install is working? It says "Configuring MTGArena", but it's been there for a while. Obviously I can't tell if the bar is advancing given the graphical hiccup
Game Update
by Diogo Kersting on Thursday October 4th 2018, 16:32
If anyone is having trouble updating the game, it's probably that you'll need to download the newer installer, and install the game again from scratch.

Apparently some updates can only be executed by `MtgaLauncher.exe` which doesn't seem to work with wine-3.17-staging.
In my case I started with a new wine configuration, and reinstalled with the newest version of the installer available on the Magic Arena website and was able to play normally.
RE: Game Update
by Musang on Friday October 5th 2018, 7:40
Additionally, it is possible that redownloading the installer and rerunning it will not properly patch the game (lobby loads but matchmaking doesn't work). This is due to the fact that the game will download only the necessary files on top of the current installation but will not successfully produce a working installation.
To fix this, first uninstall the game entirely, then reinstall the newest version from the website.
RE: Game Update
by Miguel on Friday October 5th 2018, 10:29
Yep, I had this happen. I was able to start the launcher which patched the game, and then the lobby loaded fine, but it failed to load the actual game beyond the lobby. I will try reinstalling
Game stuck at preparing assets
by Banars on Thursday October 4th 2018, 9:00
OS: MacOS High Sierra 10.13.6
Wine Ver: 3.17 Stagging
Winecfg to Windows 10

Game started and finished downloading al parts. After that a window crash app showed up and then an other window saying that there was a program error and game closed.

Then I realised I was using windows 7 so changed it to windows 10.

Now when I open the game it stucks at "preparing assets" until mac activity monitor shows it stopped working.
GetThreadContext failed
by Dbr on Saturday September 29th 2018, 0:25
I am using 3.16 and set my winecfg to Windows 10. I was able to play closed beta, but open beta will not patch.
RE: GetThreadContext failed
by Musang on Saturday September 29th 2018, 9:50
The error "GetThreadContext failed" seems to be commonly reported while the application downloads and installs files. Relaunch the application after the error or failing that, redownload the application from the given URL. That seems to work for most people.
RE: GetThreadContext failed
by Dbr on Saturday September 29th 2018, 16:51
These are my results from downloading the files. Tried both wired and wifi. I would not rate this wine install gold based on the install process alone.
file of total
And still trying.
RE: GetThreadContext failed
by Musang on Sunday September 30th 2018, 12:54
So it seems that the issue has been pinpointed roughly in bug

The short of it is that it's unstable mono behaviour by unity's mono runtime. The thread suggests to set the environment variable WINEDEBUG=+relay,-debug
Other than that, as suggested clean reinstall, update wine, retry...
To be fair I've seen people complain about this exact issue on windows so I'd say that the issue is upstream of wine at this point.
RE: GetThreadContext failed
by Odedi on Saturday September 29th 2018, 13:47
Try reinstalling the whole thing, on windows switching to beta requires the launcher executable, which doesn't work properly on wine.
