Quick Answer
lectora.exe is safe. It is the official Lectora desktop authoring tool by Trivantis, using distinct processes for editing, rendering previews, and background tasks.
What is lectora.exe?
lectora.exe is the executable for the Lectora Desktop Authoring Tool, used to build, edit, and publish e-learning courses. It launches several helper processes to manage the UI, assets, autosaves, previews, and cloud syncing as you work.
Lectora uses a multi-process architecture to separate UI, autosave, rendering, and cloud sync tasks. This design improves stability and responsiveness during project development and playback previews.
Quick Fact: Lectora's editor uses separate processes for UI, rendering, and autosave to keep the interface responsive even with large projects.
Types of Lectora Processes
- UI Process: Main user interface and project navigation (1 instance)
- Renderer Process: Preview rendering and timeline playback
- Asset Manager: Media import, caching, and asset library
- Cloud Sync: Syncs projects with Lectora Cloud and backups
- Autosave/Backup: Background saves and recovery points
- Utility/Background: Background tasks like licensing checks and updates
Is lectora.exe Safe?
Yes, lectora.exe is safe when it's the legitimate file from Trivantis/ Lectora downloaded from official sources (Trivantis.com or included with the Lectora installer).
Is lectora.exe a Virus or Malware?
The real lectora.exe is NOT a virus. However, malware sometimes disguises itself with similar names. Always verify the digital signature.
How to Tell if lectora.exe is Legitimate or Malware
- File Location: Must be in C:\Program Files\Lectora\ or C:\Program Files (x86)\Lectora\; any lectora.exe elsewhere is suspicious.
- Digital Signature: Right-click the executable in File Explorer → Properties → Digital Signatures. Should show "Trivantis LLC".
- Resource Usage: Normal usage is 2-18% CPU per process, 120-520 MB total memory; persistent high usage when idle is suspicious.
- Behavior: Lectora should launch when you start Lectora. Background processes unrelated to a running UI are unusual.
Red Flags: If lectora.exe is located in unusual folders (like AppData, Temp, or System32), runs when Lectora isn't open, has no valid digital signature, or uses constant, abnormal resources, scan with antivirus.
Why Is lectora.exe Running on My PC?
lectora.exe runs when you open Lectora or when it is configured to perform background tasks such as autosave, cloud sync, or rendering previews.
Reasons it's running:
- Active Project Editing: You're actively editing or previewing a project; UI and render tasks run in separate processes to keep the interface responsive.
- Background Sync and Cloud Backups: Lectora Cloud integration may run in background to sync assets and backups.
- Autosave and Backups: Autosave points and backups run regularly to prevent data loss.
- Preview Rendering: Rendering previews in real-time or for export creates additional processes.
- Startup or Background Service: Lectora may launch on Windows startup or enable background services for licensing checks.
Can I Disable or Remove lectora.exe?
Yes, you can disable lectora.exe. It's safe to close Lectora when not in use, and you can uninstall Lectora or disable startup if needed.
