You have client issues?
On this page you can find tips and tricks how to solve your problems whatever they are!
But please note, these tips and tricks are for Windows 7 or newer!
If you're running windows older than 7, such as Vista, XP m.m.. There aren't much support due to the fact that it's recommended to have windows 7 or newer for MasterCores client.


General Tips and Explanation of the client
The application you download from the website and run to open the client is called a Loader.
This is the application that start the client and make sure it's okay and up to date.
The small box "MasterCores Launcher" is the client loader, it will be the first one to show itself before the actual game opens.
Shortly after the game is opened, the loader will close itself automatically.
And the big box "MasterCores" is of course the client, the final game window.

When running the client, mind where you run it from!
As with many other games, you should always avoid starting them from the C:/ disk (the disk which your operation system is stored).
It's recommended that you store the game on another disk, like D:/, E:/ or whatever disks you might have.
If you don't have additional harddrives for your computer, you can store the client on your desktop, but make sure to run the game as "administrator" to avoid access issues.

Having the client on desktop or on C:/ drive might prevent the client from having enough access to read/write to its own files.
And that may cause the game to appear glitchy, and even make the game unable to save hotkeys, minimap and other settings.
Therefor, avoid C:/ drive for games, and if not possible, always run as admin (right click > run as admin).

If you aren't too experienced in computers and the text above seems to be in an alien language, please find someone who can help you out and explain it to you or help you set it up.

Client loader wont start
Gives error or crashes The loader can run on most systems that's newer than windows 7, even if they're not updated, if you can't start the loader it means you don't have right drivers installed on your system.
Go to your control panel and check if windows has any updates for you!
The important ones is .NET updates.
Nothing happens If absolutely nothing happens, it means most likely that an antivirus is blocking it from starting.
You can test if the antivirus is affecting the loader by shutting it off and try to run the loader with the antivirus off.
If the loader starts working then, you just need to whitelist the loader in the antivirus.
Notice: Sometimes antiviruses "Ban" folders, so even with the antivirus off, the folder might still be banished and you can't use anything in it.
Solve that by downloading a new client, to a new folder with different name.
If the new folder works, but old doesn't, then you know the antivirus banned that folder and you might as well delete the old folder.
Loader disappears If the launcher disappears it's caused by your antivirus that thinks the loader is a virus.
To avoid this, either whitelist the entire game folder or the loader in your antivirus.
You can confirm it's the antivirus deleting the client by completely disabling it for a moment while you try to run the loader.
Antivirus blocked the client but even as off, client wont start Antiviruses often makes a "folder banishment" that makes anything within the client folder not being usable in any way.
To go around this, you need to download a fresh client and place it in a new folder with a different name.
Try starting the new client to confirm it works, after that, try experiment with the antivirus, try to whitelist the entire client folder.
We want the antivirus to be able to run while we play MasterCores.

Missing Drivers

Missing visual C++ drivers
Download Visual C++ 2019 x86 and install it on your computer.
if problem continue, download Visual C++ 2019 x64 and install it on your computer.

Missing drivers
Download Visual C++ 2019 arm64 and install it on your computer.

Missing directX drivers
Download MicroSoft DirectX, create a new folder (on your desktop or wherever you'd like to), run the file and change the extraction path to the new folder.
This is because when it extract, it will extract multiple files without a folder.
Once it's unpacked, you enter the new folder you created and find DXSETUP.exe and run the application, follow the steps and install it.
Beware Always make sure your Windows is up to date, check if there's any updates available.
Steps: Start > Settings > Update & Security > Check for updates.

After installing drivers, you may need to restart your computer for it to work properly.
Often it works without a restart, but if you recently installed something and it doesn't work, restart your computer.
