Troubleshooting Corepunk Issues

I decided to create this mini-guide/information website until AC ships out a new version of launcher with the issues resolved to help people with installing the game.

Installation Guide

1. Download the portable .zip launcher from https://corepunk.com/en-us/download

2. Create a new directory called "CorepunkLauncher" (or any name you prefer) in a location that is not a protected system directory.

3. Move all files from the .zip into the newly created "CorepunkLauncher" directory.

4. Run Corepunk Launcher.exe


Login Guide

1. Click the Login button inside the launcher.

2. A website https://auth.corepunk.com should open with a lengthy link.

3. Log into the website using your account.
3.1. If you don't have an account, click "Register as new user" at the bottom of the website. Then, close the browser, return to the launcher, and click Login again to log in with your newly created account.
4. You will be prompted to confirm your account's email address. If the email does not arrive within a few seconds, click Resend Email.

5. You will be prompted to Activate Game Key. Again a website will opeen and navigate you to key activation screen.
5.1. Input your key from email received in the visible field and press Activate.
5.2. Click red "Activate" text right next to the key that now should be visible in your activated keys list to confirm activation.
6. Select the installation destination for the game. By default, it will be installed in: C:\username\Documents\Games | Universal path: %userprofile%\documents\Games

7. A game download should start.


Common purchase/email issues.

  • I bought the Founder Pack, but there is no email with the Key!

    If you purchased the game using your PayPal account, and the email associated with that PayPal account differs from the email you provided during the purchase process, the order and key will be sent to the email address linked to your PayPal account.

    The key may take anywhere from couple seconds to few minutes to be sent to your email. First, check all of your inbox labels or tabs (For gmail often lands in "Offers", Spam etc.) to see if it has ended up there.


  • I Get the "You are not logged in" Screen or "not-found" blank website with just image

    If you clicked the login link from the email with the key or purchase order, simply go to auth.corepunk.com and manually create an account at the bottom of the page.

    Otherwise try syncing your windows time. Right click windows Clock -> Adjust date/time -> Sync Now


  • I bought the founder pack but key cannot be activated

    For people who bought Founder packs in the first wave months ago (with 403/405 packs) or people who should have their free account for being an A2 tester reach out to support@corepunk.com about it providing your email, alpha 2 key email screenshot or key, proof of purchase (if u don't have it, still feel free to reach out anyway).



Launcher cannot be downloaded or shows a virus warning from browser or antivirus

If you're unable to download the launcher from https://corepunk.com/en-us/download or encounter a virus warning:

1. Disable your browser's Safe Browsing feature temporarily:
- Google Chrome: Go to chrome://settings/security then switch off Safe Browsing.
- Microsoft Edge: Navigate to Settings > Privacy, Search, and Services, and turn off the SmartScreen for Microsoft Edge feature.
- Mozilla Firefox: Go to Settings > Privacy & Security and uncheck the option under Deceptive Content and Dangerous Software Protection.

2. Download the .zip file. Once the download is complete, re-enable the browser's Safe Browsing feature (or its equivalent) to protect against future threats.

3. If your antivirus flags the file instead of the browser, create a new folder where you wish to unpack the zip file, add this folder to your antivirus' exceptions list, and then unzip all the corepunk-launcher-production.zip content (move by dragging) into this directory you added to exceptions. Tutorial how to add exceptions

4. If the game is blocked or removed when you attempt to run it, add the game's installation directory to your antivirus' exceptions list as well.


Localhost cannot be reached / refused to connect to auth.corepunk.com

If a solutions below don't work or you haven't tried yet, also try running launcher as admin (Right click > Properties > Compability > check "Run as administrator" > Apply).

Check if the login server is online
First, manually open https://auth.corepunk.com in your browser.
If the page does not load, the login server may be offline or inaccessible at this time. Wait and try again later.

Sync your system time
Incorrect system time can cause connection issues. To resolve this:
1. Open the Time & date settings in Windows.
2. Click the Sync now button to ensure your system time is accurate.
3. Retry running the launcher after making these changes.

Delete broken login file
1. Hit Windows key+R on your keyboard and input %localappdata% then hit enter.
2. Navigate to Artificial Core > Corepunk folder.
3. Delete start.dat file.
4. restart the launcher as administrator.

Adjust network adapter settings
If you use a VPN or have multiple network adapters installed, the launcher may not know which adapter to use for returning the request. To fix this:
1. Open Network & Internet settings in Windows.
2. Go to Change adapter options.
3. Disable all network adapters except the one providing your internet connection.
4. Retry running the launcher after making these changes.


Update button being stuck

1. Click the wrench icon
2. Press uninstall
3. install again

If you don't want to redownload entire game (slow internet or other reasons) you will need to press Windows+R on your keyboard and delete LauncherSettings.json file from inside Artificial Core\Corepunk Then close and open launcher again.

If you have game installed in non-default location the launcher will show "Install" button. Don't press it, instead close launcher and navigate to LauncherSettings.json again and alter the "GameRootFolder" value to your game client path (remember about double slashses \\ in .json paths), then add following lines after "GameRootRCFolder"
"GameVersion": "187",
"GameCommand": "Corepunk.exe",


Fixes above didn't work

Start from the scratch:

1. Download and Install the New Launcher: Download the latest version of the launcher from the official website. Delete the old launcher from your system, then extract the new launcher from the .zip file into the same folder as the previous launcher.

2. Synchronise Your Windows Time: Right-click the clock on your taskbar and select Adjust Date/Time. Click Sync Now.

3. Clear Old Data: Press Windows + R to open the Run dialog box. Type %localappdata% and press Enter. Locate and delete the folder named Artificial Core.

4. Launch the New Launcher: Open the newly installed launcher.

5. Optimise CPU Affinity Settings: Press Ctrl + Shift + Escape to open Task Manager. Navigate to the Details tab, find Corepunk Launcher.exe, right-click it, select Set Affinity, and set it to use only CPU cores 0, 2, 4, 6.

6. Complete the Login and Download Process: Log in through the launcher and begin the download and update process.
