Hello fellow Aion adventurers,
If you're encountering issues with your game launcher, kindly follow the steps outlined below carefully.
1. Should the launcher fail to start entirely (initiating euroaion.exe triggers an immediate Windows error) - ensure you install these programs:
1 - DirectX. Download the crucial version (June 2008) via this link. PAY ATTENTION! Running the downloaded file requires a path for unpacking the files. It is not installing! Again, it's just unpacking! Open the folder you designated and run the installer - DXSETUP.
2 - Microsoft Visual C++ Acquire the necessary files via the official site through this link and proceed with installation.
3 - Make sure to download and install NET Framework, which is critical for proper launcher functioning!
2. Launch the installer. Navigate to the launcher settings to specify the game directory path (either currently downloaded or future download location) and opt for "torrent" as the download method. Choose the client type (64bit recommended) and set the game language.
3. Pause any downloading/sharing processes through the torrent, and ensure no other game window is open.
4. Add the game directory and the launcher to your antivirus exclusions (Note: absence of dedicated antivirus software doesn't imply immunity, as Windows Defender/Security acts as a default antivirus; this recommendation applies to it as well).
How to do this in Windows Defender/Security?:
Hit WIN (Start) > Search for "Virus and threat protection" > Access.
Navigate to "Virus and threat protection settings", hit "Manage settings".
Locate the "Exclusions" area and select "Add or remove exclusions" > "Add an exclusion" > "Folder" > Locate your game folder.
Verify the launcher resides within this directory. Otherwise, exclude the launcher file separately.
5. Right-click on the game folder > Properties > Uncheck "Read only". Click "Apply" > "Apply changes to this folder, subfolders and files".
6. Ensure you didn't BLOCK the launcher connection on first launch.
You may have been prompted by a firewall request (example shown below):
Failure to permit this connection will inhibit launcher functionality.
Rectification steps:
Select Windows (Start) > Find "Firewall" > open "Windows Defender Firewall" > From the left menu, click "Allow an app or feature through Windows Defender Firewall" > Select "Change settings"
Beneath the table, find "Allow another app" > "Browse" > Navigate to your game folder and select Euroaion.exe > Click "Add". Add a second file too! Check here: "Your game folder\bin64\ActiveLauncher.exe" or "Your game folder\bin32\ActiveLauncher.exe" - for 32bit client usage. Feel free to add both to the exclusions. Tick the boxes for both "private" and "public" networks:
If after these steps the launcher still doesn't work, your internet service provider might be obstructing our services. Our systems employ anti-DDOS measures, occasionally blocked by local ISPs (notably in Russia). These protections are essential; there's no workaround. At this stage, it's an ISP policy issue, not a server problem.
In some cases, either your ISP or country might restrict torrenting activity.
Use VPN to surpass these limits.
Experiment with free and paid VPN services (some free options might be ineffective). Ensure your chosen VPN handles all your traffic, not just post-login (as some ping-reduction tools do). Once the game starts, feel free to disconnect the VPN for improved ping.
Other potential issues:
If your launcher displays a loading animation or an unhappy face in place of news:
This signals you overlooked the steps mentioned above, affecting launcher connection stability.
Despite this, the game might launch if downloaded fully, thanks to different servers. Push "Play", and skip the news section.
This sometimes occurs due to torrent peculiarity. Stay patient! Try restarting the download. If torrents are ineffective, VPN is your solution.
Should the download stall for an extended period (over 10 min), it represents a connection issue, necessitating adherence to the outlined steps.
This situation is conventional. Sometimes small data files lead to delays. Allow around 10 minutes.
If unresolved, examine missed procedures (often other processes might be using your game client files, thwarting updates).
You neglected the prescribed actions. The launcher's inability to establish permissions halts file loading.
You skipped prescribed procedures. Launcher cannot overwrite a file (due to permissive constraints such as "read only" mode, game in play, or torrent-related activities).
An updated launcher version can be manually obtained from here, though automatic update via initial instructions is preferable.
IMPORTANT. IF EVERYTHING FUNCTIONED PREVIOUSLY, VERIFY IT'S NOT OUR SYSTEM'S FAULT BEFORE DELETING GAME FILES, UPDATING THE CLIENT, OR DOWNLOADING ANEW. IF MANY SHARE YOUR ISSUE, JUST WAIT.
If your issue persists despite following above instructions, reach out via our Discord, and open a ticket for assistance.
