What causes a game that will not start for some players?

A missing runtime (Visual C++ redistributable, .NET), an outdated GPU driver, an unsupported instruction set, or antivirus blocking the executable stops the game before it can log anything.

How do I catch this when it only happens for some players?

Capture it automatically from the player's device with the full stack trace, the device and OS, the build, and a breadcrumb trail of what they did. That turns a vague complaint into a specific, reproducible issue you can fix without owning the hardware it happens on.

How to Fix a Game That Won't Start for Some Players

Quick answer: Capture launch failures with a crash handler that runs before the engine, document and bundle required runtimes, and check for driver and CPU-feature requirements players may not meet.

A game that does not start for some players fails before your normal logging exists, which makes it feel invisible. Capturing the early failure and checking prerequisites finds it. Here is how.

How to fix it

1. Capture the earliest failure

Launch failures happen before the engine initializes, so in-game logging never runs. A crash handler that installs at process start, or the OS event log, captures the fault that ordinary logging misses.

2. Bundle and check runtimes

Missing redistributables (Visual C++, .NET) are a top cause. Bundle and install them, and document requirements. The same goes for GPU drivers below your minimum and CPU features your build assumes.

3. Rule out antivirus and permissions

Unsigned executables get quarantined and some folders are write-protected. Sign your build, and ensure it does not need to write where it lacks permission, so it launches on a locked-down machine.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every your game error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.

Ship the fix, watch the signature disappear from the next build. That's how you know it's really gone.
