What is rider64.exe?
rider64.exe is the Windows 64-bit launcher for JetBrains Rider, a cross‑platform IDE for .NET development. Rider combines the IntelliJ platform with a rich set of .NET tools, and it spawns multiple background tasks to index code, analyze defects, and manage plugins as you edit and build projects.
Rider runs on the JetBrains Runtime (JBR) and uses a modular, multi-process architecture to separate UI, indexing, and tooling, enabling stable editing and fast feedback even in large solutions.
Quick Fact: Rider leverages a JVM-based runtime and background daemons for code analysis, ensuring responsive editing even for big C# projects.
Types of Rider Processes
- Main IDE Process: User interface, project view, and tool windows (1 instance per session)
- Indexer/Daemon: Background indexing and symbol resolution for fast searches
- Code Analysis/Inspections: On-the-fly code analysis and quick-fix suggestions
- Plugin Host: Isolated processes for installed plugins to prevent crashes from affecting the IDE
- Build/Runner: Handles compilation tasks via the selected .NET SDK
- JBR Runtime: JetBrains Runtime that runs the IDE itself
Is rider64.exe Safe?
Yes, rider64.exe is safe when it is the legitimate JetBrains Rider installer/executable from JetBrains and located in the official installation folder.
Is rider64.exe a Virus or Malware?
The real rider64.exe is NOT a virus. Malware can mimic names; always verify the file location and signature.
How to Tell if rider64.exe is Legitimate or Malware
- File Location:: Must be in
C:\Program Files\JetBrains\Rider 2025.1\bin\ or C:\Program Files (x86)\JetBrains\Rider 2025.1\bin\. Any rider64.exe elsewhere is suspicious.
- Digital Signature:: Right-click the file in Explorer → Properties → Digital Signatures. Should show signed by "JetBrains s.r.o."
- Resource Usage:: Normal usage is a few percent CPU per tab plus background indexing; consistently high CPU with no IDE window open is suspicious.
- Behavior:: IDE should run when you start Rider and should not create processes in user directories like Temp or AppData without cause.
Red Flags: If rider64.exe is located in unusual folders (Temp, AppData, or System32), runs when Rider isn't open, has no digital signature, or uses excessive resources constantly, scan your system with antivirus software immediately. Beware of similarly-named files like "rider64.exe" from untrusted sources.
Why Is rider64.exe Running on My PC?
Rider starts when you launch the IDE or when it is configured to run in the background to speed up load times and keep project indexing up to date.
Reasons it's running:
- Active IDE Use: You opened a Rider project; the main process and indexers run to support editing, building, and navigation.
- Background Indexing: Rider indexes libraries and project files in the background to provide fast search and code insight.
- Automatic Project Sync: Rider periodically syncs with the project’s .NET SDK and NuGet dependencies to keep references current.
- Plugins and Inspections: Active plugins perform analysis and feature enhancements; each plugin can run in its own thread or process.
- Startup/Restore State: Rider restores the previous session state and loads caches to resume work quickly after launch.
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 it or disable background features if desired.
How to Stop rider64.exe
- End IDE Session: Close Rider via the X button or File → Exit; ensure all projects are saved.
- Close Background Tasks: In Settings → Appearance & Behavior → System, disable background tasks if available.
- Terminate Process: Open Task Manager, locate rider64.exe, right-click → End Task
- Disable Startup: Task Manager → Startup tab → Disable JetBrains Rider
- Uninstall Rider: Windows Settings → Apps → JetBrains Rider → Uninstall
How to Uninstall Rider
- ✔ Windows Settings → Apps → Apps & Features → JetBrains Rider → Uninstall
- ✔ Control Panel → Programs → Uninstall a program → JetBrains Rider → Uninstall
- ✔ Remove leftover configuration: delete C:\Users\<User>\AppData\Roaming\JetBrains\Rider2025.1 and C:\Users\<User>\.Rider2025.1
Common Problems: High CPU or Memory Usage
If rider64.exe is consuming excessive resources:
Common Causes & Solutions
- Large solution indexing: Let Rider index gradually; you can pause indexing in Settings → Appearance & Behavior → System or adjust indexing scope.
- Heavy plugins: Disable or uninstall unnecessary plugins in Settings → Plugins
- Many open projects or huge dependencies: Close unused projects or use solution-wide search with scoped indexing
- Outdated Rider: Update Rider to the latest version from JetBrains Toolbox or the official download page
- JetBrains Runtime mismatch: Ensure you’re using the bundled JBR; reinstall Rider if in doubt
- Corrupted caches: Invalidate caches / Restart in File → Invalidate Caches / Restart
Quick Fixes:
1. Quick Fixes:
2. 1. Close unused projects and editors
3. Invalidate caches: File → Invalidate Caches / Restart
4. Disable unused plugins in Settings → Plugins
5. Check for Rider updates and install
6. Restart Rider to apply changes
Frequently Asked Questions
Is rider64.exe a virus?
No. The legitimate rider64.exe is part of JetBrains Rider and should be located in C:\Program Files\JetBrains\Rider 2025.1\bin with a valid digital signature from JetBrains s.r.o.
Why is Rider using so much memory?
Rider loads large projects into memory for fast analysis, indexing, and code completion. Close unused projects, disable heavy plugins, and consider increasing JVM heap size in Help → Edit Custom VM Options.
Can I delete rider64.exe?
You should not delete rider64.exe unless you intend to uninstall Rider. To remove, use Windows Settings → Apps → Uninstall JetBrains Rider.
Can I disable rider64.exe from starting automatically?
Yes. Disable startup in Task Manager (Startup tab) or adjust Rider now to start minimized and only when needed.
Why does Rider spawn many background processes?
Rider uses multiple background tasks for indexing, plugin hosting, and code analysis to keep the IDE responsive and accurate across large projects.
How do I reduce Rider's memory usage?
Close unnecessary projects, disable unused plugins, invalidate caches if needed, and consider increasing the IDE heap by editing the vmoptions file if you have enough RAM.
