Common Installation Errors & Fixes

Error	Platform	Cause & Fix
"Steam servers too busy"	PC (Steam)	Server overload; wait or restart Steam client. Verify integrity of game files (Library → Properties → Local Files → Verify).
"Insufficient disk space"	All platforms	Free up space (see storage requirements above). On PC, move game to another drive via Steam settings.
"Failed to start game (missing executable)"	PC (GOG)	Antivirus quarantined `Undertale.exe`. Exclude game folder in AV. Reinstall.
"This app can't run on your PC"	PC (Windows)	Install Visual C++ Redistributable 2015-2022 (x86). Run Undertale as administrator (right-click → Properties → Compatibility).
"Controller not working"	PC	Use XInput controller. For PS4/5, install DS4Windows. In Steam, enable Steam Input (Controller Settings → Generic Gamepad Support).
"Black screen on launch"	PC	Update graphics drivers. Disable overlays (Discord, Nvidia ShadowPlay). Run in windowed mode (`-windowed` launch option).
"Purchase not showing on console"	PS/Xbox/Switch	Check region compatibility (game is region-free, but store region must match payment method). Restart console.
"Download stuck at 99%"	Switch	Pause and resume download. If persists, archive game and redownload.
"Save file not loading"	Mobile	Ensure cross-save is enabled in both PC and mobile. Reinstall app if corrupted. Backup saves from `%LOCALAPPDATA%\UNDERTALE` on PC.
"Crash on startup (Windows 11)"	PC	Enable Windows 8 compatibility mode: `Undertale.exe` → Properties → Compatibility → Run this program in compatibility mode for Windows 8.

Post-Install Verification

After installation, perform these checks:

1. Launch the game – It should start with Toby Fox's logo, then a dark screen with music ("Once Upon a Time"). If you see a white screen, wait a few seconds; if persists, check drivers.
2. Audio test – Listen for music/sound effects. If none, update audio drivers or set default device as stereo.
3. Save test – Reach a save point (first one after intro room) and save. Exit and reload to confirm save persistence.
4. Controller test – Move character with D-pad/left stick, confirm menu navigation with A/B buttons. If not working, reconfigure per platform tips above.
5. File integrity – On Steam: Library → Undertale → Properties → Local Files → Verify integrity of game files. On GOG: GOG Galaxy → Manage installation → Verify. On consoles: No built-in verify, but reinstall if issues.
6. Update check – Ensure latest version (v1.0.1 on PC, equivalent on consoles). Console updates are automatic; Steam updates by default; GOG Galaxy checks on launch.
7. Backup saves – Windows: `%LOCALAPPDATA%\UNDERTALE` (file `file0`, `file9`, `undertale.ini`). macOS: `~/Library/Application Support/UNDERTALE`. Linux: `~/.config/UNDERTALE`. Console saves are backed up to cloud if subscribed. Mobile: sync cloud option.

Additional Tips

Modding: PC version (Steam/GOG) supports mods. Back up original `data.win` and `sound` folders before installing mods.

Cross-save (PC ↔ Mobile): To transfer, on PC, upload save to cloud (via game's built-in option; requires internet). On mobile, select "Load from cloud" during initial setup.”
