What is rider64.exe?
rider64.exe is the 64-bit launcher for JetBrains Rider, the cross‑platform IDE used for .NET and C# development. It starts the JetBrains Runtime VM and hosts the IDE user interface, code analysis, language servers, and plugin services. Rider uses multiple processes to isolate the UI, editor, and background tasks for stability and performance.
Rider runs as multiple processes under the JVM-based JetBrains Runtime. The main process handles UI and tool windows, while separate processes manage the editor, indexing, and plugins. This architecture improves responsiveness and stability by sandboxing components.
Quick Fact: Rider leverages a multi-process architecture to keep the UI responsive while background tasks index and analyze code.
Types of Rider Processes
- Main Process: UI, menus, project model, and core IDE logic
- Editor Process: Code editor rendering and in-editor language features
- JVM Process: JetBrains Runtime JVM hosting the IDE environment
- Plugin Host Process: Plugins run in their own dedicated process for isolation
- Indexing/Background Task: Background indexing, search, and project-wide analysis
- Build/Test Runner: Background tasks for builds, tests, and profiler data
Is rider64.exe Safe?
Yes, rider64.exe is safe when it's the legitimate file from JetBrains downloaded from official sources (jetbrains.com) and located under the Rider installation path.
Is rider64.exe a Virus or Malware?
The real rider64.exe is NOT a virus. However, malware can masquerade with similar names. Always verify the file path and digital signature.
How to Tell if rider64.exe is Legitimate or Malware
- File Location:: Must be in
C:\Program Files\JetBrains\Rider\bin\rider64.exe or C:\Program Files (x86)\JetBrains\Rider\bin\rider64.exe. Any rider64.exe elsewhere is suspicious.
- Digital Signature:: Right-click the file in Explorer → Properties → Digital Signatures. Should show "JetBrains s.r.o." as the signer.
- Resource Usage:: Normal usage varies; use Task Manager to confirm. Typical Rider usage is moderate while idle and higher during indexing.
- Behavior:: Rider should launch when you start the IDE. If rider64.exe runs without user action or a Toolbox trigger, scan with a reputable antivirus.
Red Flags: If rider64.exe is located in unusual folders (such as Temp, AppData, or System32), runs without launching Rider, has no valid signature, or uses high resources constantly, scan immediately. Watch for similarly named files like "rider64.tmp.exe".
Why Is rider64.exe Running on My PC?
rider64.exe runs when you start JetBrains Rider or when Rider is configured to run background tasks such as indexing, plugin services, or automatic project loading.
Reasons it's running:
- Active IDE Use: You're actively working in Rider; the IDE starts rider64.exe to render UI, manage editors, and run analysis
- Background Indexing: Rider indexes projects in the background to provide fast searches, code completion, and navigation
- Plugins and Language Services: Plugins and language servers run in separate processes to provide features without blocking the UI
- Toolbox or Startup Launch: JetBrains Toolbox or Windows startup may launch Rider automatically at login
- Telemetry and Sync: Rider may perform telemetry or settings sync with your JetBrains account, spawning background tasks
Can I Disable or Remove rider64.exe?
Yes, you can disable rider64.exe. It's safe to close Rider when not in use, and you can uninstall Rider completely if you prefer a different IDE.
How to Stop rider64.exe
- End Individual Rider Tasks: Press Ctrl+Shift+Esc to open Task Manager, select rider64.exe (and javaw.exe if present) and End Task
- Close Rider: Quit Rider from the UI or use Exit; ensure all windows are closed
- Prevent Startup: Task Manager → Startup tab → Disable JetBrains Toolbox or Rider
- Stop Background Tasks: In Rider, go to Settings → Appearance & Behavior → System Settings → Startup/Shutdown and disable startup actions
- Temporary Disable Plugins: Disable or uninstall unnecessary plugins to reduce background activity

Common Problems: High CPU or Memory Usage
If rider64.exe is consuming excessive resources:
Common Causes & Solutions
- Many files/projects open: Close unused projects or reduce open windows; consider enabling code folding and suspending background indexing when not needed
- Background indexing: Allow indexing to complete; you can temporarily disable indexing from Settings while working on large projects
- Resource-intensive plugins: Disable or remove plugins; go to Settings → Plugins and disable unnecessary extensions
- Outdated Rider: Update to the latest version: Help → Check for Updates
- Hardware acceleration issues: Toggle hardware acceleration: Settings → Appearance & Behavior → System → Use hardware acceleration when available
- Corrupted caches: Invalidate caches and restart: File → Invalidate Caches / Restart
Quick Fixes:
1. Quick Fixes:
2. 1. Use Rider Task Manager (Help → Find Action → Show Running Tasks) to identify heavy tabs or plugins
3. Invalidate caches and restart: File → Invalidate Caches / Restart
4. Disable unnecessary plugins in Settings → Plugins
5. Update Rider to the latest version
6. Enable Memory Saver: Settings → Appearance & Behavior → System → Memory Saver
Frequently Asked Questions
Is rider64.exe a virus?
No, the legitimate rider64.exe from JetBrains is not a virus. Verify the path is C:\Program Files\JetBrains\Rider\bin\rider64.exe and that it is digitally signed by JetBrains s.r.o.
Why is rider64.exe using so much CPU?
High CPU is usually caused by indexing, large solutions, or active language services. Open Rider Task Manager (Help → Find Action → Show Running Tasks) to identify culprits, then close or disable the source.
Can I delete rider64.exe?
You should not manually delete rider64.exe. Uninstall Rider via Windows Settings or Control Panel; you can reinstall later from jetbrains.com/rider.
Can I disable rider64.exe?
Yes. Close Rider, disable startup in Task Manager, and/or disable background tasks in Rider settings. You can also disable automatic startup in JetBrains Toolbox.
Why does Rider start on Windows startup?
Rider may be configured to launch at login via the Toolbox or a startup entry. Disable in Task Manager → Startup or in JetBrains Toolbox settings.
Why are there multiple rider64.exe processes?
JetBrains Rider uses a multi-process architecture to separate UI, editor, indexing, and plugins. This improves stability; you can observe tasks with Shift+Esc in the IDE.
