Even seasoned technicians encounter serial number issues. Below is a troubleshooting table for the most frequent error codes and messages related to the FANUC Ladder III serial number.
| Error Message | Probable Cause | Solution |
|---------------|----------------|----------|
| "Invalid serial number. Installation aborted." | You entered the dongle serial instead of the software install serial. | Confirm the correct number from the CD sleeve. |
| "License check failed. Dongle not found." | The USB dongle is not inserted, or drivers failed to load. | Re-insert dongle. Try a different USB port. Reinstall dongle drivers from C:\FANUC\Driver. |
| "Serial number mismatch." | The dongle’s serial does not match the one entered in the software authorization. | Run FL-III, go to Help > License Manager, and re-enter the correct dongle serial. |
| "Demo mode – 30 days remaining." | No dongle serial entered, or dongle is for a different FANUC product (e.g., Ladder II). | Purchase a valid FL-III dongle or contact FANUC for upgrade. |
| "This serial number has been revoked." | The dongle was reported lost/stolen, or a previous license transfer was incomplete. | Contact your regional FANUC office with proof of purchase. |
If you are performing a fresh installation, follow this workflow precisely. Mistakes here are the #1 cause of "invalid serial number" errors.
Step 1: Insert the FANUC Ladder III CD.
Step 2: Run Setup.exe as Administrator.
Step 3: At the Serial Number prompt, type the software installation serial (not the dongle serial yet). Ensure no extra spaces.
Step 4: Choose the installation directory (default: C:\FANUC\LADDERIII).
Step 5: When prompted, plug in the USB dongle.
Step 6: After installation, launch FL-III. It will ask for the dongle serial number. Enter the number etched on the USB key.
Step 7: Click "Authorize." If successful, the software will open fully.
Common Mistake: Swapping the two serials. The installer will reject the dongle serial during Step 3. Conversely, the software after installation will reject the installation serial.
For maintenance engineers, CNC programmers, and factory automation technicians, Fanuc Ladder III is an indispensable software tool.
