What is Fanucprg.exe (Likely)?

Based on the name and FANUC’s software ecosystem, this is almost certainly a process related to FANUC programming software, used for industrial robots or CNC (Computer Numerical Control) machines. It could be part of:

Potential Issues (Based on User Reports of similar FANUC tools)

  1. False Positives from Antivirus – Some automation software uses uncommon installation methods or communicates directly with hardware (CNC/robot controllers). Antivirus (especially McAfee, Defender, or CrowdStrike) may flag it as a “Potentially Unwanted Program” (PUP) or “HackTool” due to how it injects code or accesses memory for debugging.
  2. High CPU or Crashes – Older versions (pre-2015) of FANUC’s PC software are known to be unstable, crash frequently, or consume excessive CPU when simulating robots.
  3. Licensing Nagging – FANUC software often uses hardware locks (USB dongles) or strict license managers. Fanucprg.exe may fail to start or show errors if licensing isn’t perfect.

Error 1: "Fanucprg.exe – Application Error" (0xc0000005)

Meaning: Access violation. The program tried to read or write memory it didn’t own.

Common causes:

Solutions:

  1. Run as Administrator – Right-click ROBOGUIDE shortcut → Run as administrator.
  2. Disable antivirus temporarily (only during debugging).
  3. Repair installation via Control Panel → Programs → ROBOGUIDE → Change → Repair.
  4. Clear workcell cache – Delete contents of C:\Users\Public\Documents\FANUC\ROBOGUIDE\Cache\.
