Once you have the correct software package, typically a compressed folder containing an installer or portable application and driver files, follow these steps:
Step 1: Install the Driver First
Before connecting the programmer, install the necessary USB driver. The most common driver for EZP2020 is the WinUSB driver, often installed via a tool called zadig.exe (a generic USB driver installer) or a provided driver installer named DriverInstall.exe.
Step 2: Install the Main Software
The main software is often named EZP2020.exe or EZP_Programmer.exe.
Step 3: Connect the Hardware
Driver installation:
✅ Found a clean, non-malicious software package from a trusted forum.

✅ Verified device in Windows Device Manager.
✅ Launched EZP2020.exe and selected correct COM port.
✅ Read chip ID successfully from a known good IC.
