Game Won't Launch on a PC — What to Do

Game Won’t Launch on a PC — What to Do

Symptom: client clicks the game but it doesn’t open, crashes at startup, or shows a license error.

When This Happens

Game not included in the club library via Steam PC Cafe Program, or the license has expired
Disk protection conflicts with anti-cheat (EasyAntiCheat, BattlEye, FACEIT)
Corrupted or outdated game files (update didn’t apply due to enabled protection)
Insufficient launch permissions: game requires administrator but session runs without those rights
DirectX, Visual C++ Redistributable, or other dependency is outdated or corrupted
Disk image is outdated and doesn’t contain the latest game version

Quick Checks — Under 5 Minutes

Reproduce the problem — try launching that specific game on the neighboring PC. If it works on another PC — the problem is the specific machine, not the license.
Read the error text — write down or photograph the error message. This is the main diagnostic clue.
Check license status in Steam — open Steam on the problem PC and find the game in the library. If the game isn’t there or shows “No license” — the club license doesn’t cover this game.
Check disk protection status — in the Hall section, click the PC and look at the shield icon. Enabled protection blocks disk writes — this conflicts with several anti-cheats.
Try running as administrator — on the problem PC, find the game shortcut, right-click → “Run as administrator.” If this helps — the shortcut or permission settings need fixing.

If That Doesn’t Help — Go Deeper

Anti-Cheat Conflict with Disk Protection

This is one of the most common causes in clubs. Anti-cheats like EasyAntiCheat and BattlEye check system file integrity and write data to disk at launch. Enabled disk protection blocks this write — the anti-cheat interprets it as interference and aborts the launch.

Temporary diagnostic fix:

CRM → Hall section → PC card → shield icon → remove protection
Restart the PC via CRM
Try launching the game again

If the game launched — the cause is a conflict with protection. For a permanent fix:

Install the anti-cheat in “persistent install” mode (not in a temp files folder)
Add the anti-cheat data folder to disk protection exclusions (configured in IZI Boot parameters)
Contact IZI support — specialists can help configure the correct interaction between a specific anti-cheat and IZI Boot

Verify Game File Integrity

Game files may be corrupted if an update was interrupted while protection was enabled:

In Steam:

Open the Steam library
Right-click the game → Properties → Local Files tab
Click Verify integrity of game files
Steam will check and restore corrupted files

After verification — if files were downloaded, re-enable disk protection and recreate the image.

Update Dependencies: DirectX, Visual C++

Some games require specific component versions:

Remove disk protection
Run installers from the game folder — usually in a _CommonRedist or Redist subfolder
Install DirectX (dxsetup.exe), Visual C++ Redistributable (vc_redist.exe)
Reboot the PC and check launch
Re-enable disk protection and recreate the image

Roll Back the PC to the Reference Image

If one PC behaves differently from the rest — the fastest fix is rolling it back to the reference image:

In CRM, open the Hall section → PC card
Navigate to the IZI Boot section
Select the current reference image and start deployment
After recovery, the PC appears in the hall with “Active” status

Image deployment takes a few minutes and doesn’t require physical presence at the PC.

Steam PC Cafe Program License Errors

If the game requires activation or shows “no license”:

Ensure Steam is logged into the club account (not the client’s personal account)
Verify Steam is running in “Café” mode — a special club mode should be displayed in the Steam menu
Confirm the club license hasn’t expired — check in the Steam dashboard on the website

Prevention

Update games regularly during maintenance hours (when the club is closed), removing disk protection in advance. After updating — recreate the image.
Test new images on one PC before deploying to the whole hall.
Keep a list of games with known anti-cheat conflicts — this speeds up diagnostics when complaints arise.
Include current versions of DirectX, Visual C++, .NET in the image — this reduces the number of launch errors.

FAQ

Frequently asked questions

Game launches on one PC but not on another — why?

Most often the game version or disk image differs. If images were deployed at different times or one PC hasn't been rebooted after an update, versions may have diverged. Roll back the problem PC to the reference image via IZI Boot.

Game opens then immediately crashes — is this a club problem or the game itself?

If it only crashes at the club — most likely a conflict with the anti-cheat (disk protection may interfere) or insufficient resources (RAM, VRAM). If it crashes at home too — the problem is the game itself or the client's Steam account.

Steam prompts to log in before launching the game — what to do?

Clubs with the Steam PC Cafe Program can launch games without a personal account — through the club library. If Steam asks for a login — the game isn't in the club library or the license has expired. For licensed club games, no client account is needed.

After a Windows update, anti-cheat stopped working — how to fix?

Some anti-cheats (EasyAntiCheat, BattlEye) require reinstallation after Windows updates. Run reinstallation from the game folder: look for EasyAntiCheat_Setup.exe or BattlEye\install_BattlEye.bat. After reinstalling the anti-cheat, reboot the PC and recreate the image.

Can disk protection be removed on just one PC to update a game?

Yes. In the Hall section, click the PC → shield icon → remove protection. After updating the game, re-enable protection and reboot the PC — changes are saved in the current image. If recreating the image via IZI Boot — make updates before creating the new image.
