Build 153 was engineered for legacy Windows environments. When deploying on modern operating systems like Windows 10 or Windows 11, it is highly recommended to run the executable application ( att.exe ) in Compatibility Mode for Windows 7 and with elevated Administrative privileges to prevent database write-access errors.

Build 153 may struggle with Windows 10/11 due to older driver requirements. Running it in "Compatibility Mode" or as an Administrator is often necessary.
If you are currently running this build, stay on it—but begin planning for a migration path by 2026, as ZKTeco is sunsetting support for the 4.8.x branch. Zktime5.0 Attendance Management System-ver 4.8.7 Build153
Follow the installation wizard prompts, choosing the default directory ( C:\Program Files (x86)\AttMgt or similar).
This version is designed to serve small to medium-sized enterprises (SMEs) that rely on ZKTeco biometric devices (fingerprint, facial recognition, or RFID). Key modules include: Build 153 was engineered for legacy Windows environments
Ensure the Communication Port matches the device default (usually 4370 ).

Go to . Select your staff members and bind them to the newly created Shift. Without this step, the software will mark all attendance logs as "Unscheduled" or "Exception" entries. 6. Managing and Generating Reports
Most small businesses use the Access version because it is “install and forget.” Larger organizations or those with dedicated IT staff typically migrate to SQL Server after the first few years of data accumulation. Importantly, you can upgrade from Access to SQL Server later — the system provides tools to export existing data and import it into a fresh SQL database.
The is a highly stable, classic desktop-based time and attendance software utility developed by ZKTime5.0 . Specifically optimized for small to medium enterprises (SMEs), this exact build serves as the foundational software engine for bridging physical biometric devices with corporate payroll and human resource systems. It manages complex logic ranging from shift scheduling to real-time communication log parsing.
