Client Problem Fix

Everything you need to get the client running and to fix the most common problems.

Game won't start or crashes on launch​

Most launch problems come from missing system files on a fresh, reinstalled, or never-updated Windows. The client (NostaleClientX.exe) and the SDK (Varya.dll) need a few components that don't ship with every Windows install.

Do this first (fixes 90% of cases)​

  1. Run Windows Update completely and reboot. This installs the Universal C Runtime (api-ms-win-crt-*.dll) that the game depends on.
  2. Install the Visual C++ Redistributable — both versions. The client is 32-bit, so the x86 one is mandatory even on 64-bit Windows:
  3. Install the DirectX End-User Runtime. Needed for the DirectX 9 files the game renders with.
  4. Add the Windows Security exclusion (see below) so your antivirus stops deleting Varya.dll.
  5. Reboot and launch the game.

Error messages and their fix​

If the game shows a ... .dll is missing / was not found error, match it here:

Error messageFix
VCRUNTIME140.dll, MSVCP140.dll, msvcp140_atomic_wait.dll missingInstall the VC++ x86 + x64 redistributables. These files also ship in the game folder — if they vanished, your antivirus removed them: repair the client and add the exclusion.
api-ms-win-crt-runtime-l1-1-0.dll missingRun Windows Update fully. On Windows 7/8.1: install KB2999226.
d3dx9_43.dll / d3dx9_XX.dll missing, or black screen at startupInstall the DirectX End-User Runtime.
discord_game_sdk.dll missingRepair / re-download the client from the launcher (this file ships with the game).
Game closes instantly with no messageSee the Event Viewer tip below to find the exact missing file.
Find the exact missing file

If the game closes with no clear message:

  1. Open Event Viewer → Windows Logs → Application
  2. Find the red Error entry for NostaleClientX.exe at the crash time
  3. The description names the missing module (e.g. VCRUNTIME140.dll)

Then apply the matching fix from the table.

Never delete Varya.dll

Varya.dll is the SDK — the game will not work without it. Some antivirus programs flag it as a false positive and quarantine it. If it disappears after an update, your antivirus removed it: add the exclusion first, then repair the client.

In-game "ERROR CODE" messages​

If you can log in but every action is blocked by a red message like:

[ERROR CODE: X]: An error occured while handling your request please contact us on our support discord!

…it means the SDK (Varya.dll) is not loaded or not verified correctly. The server refuses your actions until the client is valid. Almost always the cause is: the game was launched without the SDK, or your antivirus removed Varya.dll.

CodeWhat it meansHow to fix
1The SDK did not load — the client is running without Varya.dll.Always start the game through the official launcher, never by opening NostaleClientX.exe directly. Make sure Varya.dll is in the game folder (add the antivirus exclusion), then repair the client.
2An unauthorized / injected DLL was detected (anti-cheat protection).Close any cheat, trainer, injector, or overlay tool, then relaunch the game.
3The client did not send a valid HWID (hardware ID).Restart the client. Do not run it inside a VM / sandbox or with tools that spoof or block hardware IDs. If it persists, reboot the PC.
4The SDK verification packet was not received — the security handshake did not complete.The SDK started but couldn't verify itself: this is usually a missing runtime. Follow the Game won't start steps (VC++, Windows Update, exclusion) and restart.
tip

Every ERROR CODE comes down to the same thing — the SDK isn't running properly. If you fix the startup problems (install the runtimes, add the antivirus exclusion, launch via the launcher), all of these disappear.

Windows Security exclusion​

Windows Defender (or another antivirus) may wrongly flag Varya.dll and delete it. Add your NosVarya Game folder as an exclusion so this never happens.

  1. Open Settings → Privacy & security → Virus & threat protection (Windows 10: Settings → Update & Security → Windows Security → Virus & threat protection)
  2. Under Virus & threat protection settings, click Manage settings
  3. Scroll to Exclusions and click Add or remove exclusions
  4. Add an exclusion → Folder → select your whole NosVarya Game folder
tip

Excluding the whole folder covers Varya.dll, NostaleClientX.exe and every game file at once — you don't need to add them one by one.

Update your graphics drivers​

Outdated graphics drivers are a common cause of crashes, black screens, and low FPS. Install the latest driver for your GPU, then reboot:

caution

If you still get visual glitches after updating, run NtConfig.exe in your game folder to lower the in-game graphics settings.

Launcher too large / can't click Start​

On laptops or high-DPI screens the launcher can appear oversized, hiding the Start button.

Easiest fix — the scale button: at the bottom of the launcher there's a % button (e.g. 100%). Click it and pick a smaller value (90% → 50%) until it fits. Your choice is saved automatically.

If the launcher is too big to even reach that button, set the scale manually:

  1. Open your NosVarya Game folder
  2. Open (or create) a text file named scale.txt
  3. Write a value between 0.5 and 1.0 (e.g. 0.7), save, and restart the launcher
ValueBest for
1.0Full HD (1920×1080) or higher
0.81600×900 / 1366×768 laptops
0.7Small screens or high DPI scaling
0.5–0.6Very small screens

Still blurry or oversized? Override Windows DPI scaling: right-click the launcher .exe → Properties → Compatibility → Change high DPI settings → check Override high DPI scaling behavior → select Application → OK → Apply, then restart the launcher.
