Troubleshooting eTimeTrackLite: A Complete Guide to Solving Common eSSL Errors

Regular Backups: The software has a built-in backup utility. Schedule it to run every night at 11 PM. Save the backup to a different drive or cloud storage.
UPS Protection: SQL databases corrupt easily during power cuts. Ensure the PC running eTimeTrack Lite is on a UPS.
Software Updates: eSSL releases updates frequently to patch memory leaks and SDK issues. Do not run versions older than 2 years.
Dedicated PC: Avoid installing other heavy software on the same PC running eTimeTrack Lite to prevent database resource contention.

Firmware update failed / device bricked

Install the Microsoft Access Database Engine 2016 Redistributable (choose the 32-bit version even on 64-bit Windows because Etimetracklite is a 32-bit app).
Run as Administrator: Right-click Etimetracklite shortcut → Properties → Compatibility → Check "Run this program as an administrator".
Change Temp Path: Go to Environment Variables and set TMP and TEMP to C:\Temp (create this folder first and give Everyone full control).

Clear device logs (after backup):
Device menu → Data Management → Clear Attendance Logs
Update device firmware via Device Manager → Firmware Upgrade
Re-enroll fingerprint and upload again using User Sync tool

Fix: If devices go offline, restart the service via Services.msc → Search for "ESSL Device Manager" → Restart.
Advanced: Use the DCM log viewer (DCM_Log.txt) to see exactly which IP or COM port is failing.
