1. Restart Your PC
Start with a complete restart.
Close Planetarian: The Reverie of a Little Planet, Steam or your game launcher, then restart Windows. After rebooting, launch Planetarian: The Reverie of a Little Planet before opening other demanding applications.
This can clear temporary processes and memory-related problems that prevent the game from starting correctly.
2. Run Planetarian: The Reverie of a Little Planet as Administrator
Permission problems can sometimes prevent a game from accessing required files.

- Right-click it.
- Select Properties.
- Open the Compatibility tab.
- Enable Run this program as an administrator.
- Click Apply > OK.
- Launch the game again.
If this doesn’t help, you can disable the option afterward.
3. Verify Planetarian: The Reverie of a Little Planet Game Files
A corrupted installation is one of the first things to rule out.
Steam
- Open Steam > Library.
- Right-click Planetarian: The Reverie of a Little Planet.
- Select Properties.
- Open Installed Files.
- Click Verify integrity of game files.
- Wait for the process to finish.
- Restart the game.

- Select Manage > Verify.
- Wait for verification to finish.
Try launching Planetarian: The Reverie of a Little Planet again after the repair completes.
4. Update Your GPU Driver
An outdated or corrupted graphics driver can cause a game to crash before reaching the main menu.
Update your driver using the official software for your graphics card:
- NVIDIA
- AMD
- Intel
After installing the driver, restart Windows and launch Planetarian: The Reverie of a Little Planet again.
If the crashes started immediately after a driver update, testing a previous stable driver may also help.
5. Disable Overlays
Overlays can sometimes conflict with games during startup.
Temporarily disable:
- Steam Overlay
- Discord Overlay
- Xbox Game Bar
- NVIDIA Overlay
- AMD Overlay
- Recording or monitoring software
Then restart Planetarian: The Reverie of a Little Planet.
If the game launches normally, enable the overlays one at a time to identify the conflict.
6. Close Background Applications
Heavy background applications can consume CPU, RAM, or GPU resources before Planetarian: The Reverie of a Little Planet even starts.
Press Ctrl + Shift + Esc to open Task Manager.
Close applications you don’t need, especially:
- Web browsers with many tabs
- Recording software
- Other game launchers
- Hardware monitoring tools
- RGB/control utilities
- Resource-heavy applications
Don’t end Windows system processes unless you’re certain they’re safe to close.
7. Reset Planetarian: The Reverie of a Little Planet Graphics Settings
A damaged or incompatible graphics configuration can cause the game to crash immediately after launch.
If Planetarian: The Reverie of a Little Planet provides a safe mode, reset settings, or launch-options feature, use it to start the game with default graphics settings.
If you can reach the graphics menu, temporarily use:
- Default graphics preset
- Lower resolution
- Disabled ray tracing
- Disabled frame-generation features
- Disabled advanced effects
Restart the game after applying the changes.
8. Disable Third-Party Mods and Tweaks
If you’ve installed mods, reshade filters, custom DLL files, trainers, or other modifications, temporarily remove them.
Launch the unmodified version of Planetarian: The Reverie of a Little Planet and test again.
Game updates can make previously working modifications incompatible.
9. Check Windows Updates
Make sure Windows is up to date.
Go to:
Settings > Windows Update
Install available updates and restart the PC.
This is particularly important if Planetarian: The Reverie of a Little Planet started crashing after a major Windows, driver, or game update.
10. Repair Required Windows Components
Some PC games depend on Microsoft components such as DirectX and Microsoft Visual C++ Redistributable.
If Planetarian: The Reverie of a Little Planet suddenly stopped launching, repairing or reinstalling the required components can help.
Use the installers supplied with the game when available, or obtain them from Microsoft’s official sources.
11. Check Your Antivirus or Security Software
Security software can occasionally block a game’s executable or related files.
If your antivirus has quarantined something related to Planetarian: The Reverie of a Little Planet, review its notifications and make sure the game installation hasn’t been blocked.
Don’t permanently disable your antivirus just to launch a game. If you believe there’s a false detection, use your security software’s trusted-app or exclusion feature carefully.
12. Check Available Storage
A nearly full system drive can cause unexpected problems with Windows, temporary files, shader caches, and game updates.
Open File Explorer > This PC and check your available storage.
If the drive is almost full, remove unnecessary files and make some free space before launching Planetarian: The Reverie of a Little Planet again.
13. Check for Overheating
If Planetarian: The Reverie of a Little Planet crashes immediately after loading demanding graphics, check your CPU and GPU temperatures.
High temperatures can cause instability, especially if the PC has airflow or cooling problems.
Make sure:
- PC fans are working
- Air vents aren’t blocked
- The system isn’t overheating
- Your GPU and CPU aren’t being aggressively overclocked
If you’ve manually overclocked your hardware, temporarily return it to default settings.
14. Reinstall Planetarian: The Reverie of a Little Planet
If Planetarian: The Reverie of a Little Planet still crashes on startup after trying the fixes above, reinstalling the game is the final software troubleshooting step.
Before reinstalling:
- Verify the game files.
- Remove incompatible mods.
- Update your GPU driver.
- Make sure Windows is updated.
A reinstall won’t fix crashes caused by faulty hardware, overheating, drivers, or Windows problems, so it shouldn’t be the first solution.
