It looks like you’re asking for a download link to Willar Programmer software for Windows 10.
However, I couldn’t find any legitimate or widely known software called “Willar Programmer” in official sources (like developer websites, GitHub, Microsoft Store, or major tech directories).
Here’s what you can do to find it:
Double-check the spelling — It might be:
Willar → possibly Willar as a brand (uncommon)
Programmer → maybe a USB programmer for chips (like CH341, TL866, etc.)
Could be a misspelling of “WILLAR” (some small electronics tool)
If it’s for programming microcontrollers (e.g., AVR, PIC):
Try searching for “Willar USB programmer software” on the manufacturer’s site if you have the device.
Look for any CD image or driver disk from the product packaging.
If you meant something else:
Willar could be a typo for Visual Studio (programming software for Windows 10) — official link: visualstudio.microsoft.com
Or Willar → Willer (unknown), or Willar as a company name?
To keep you safe:
Avoid downloading “Willar Programmer” from unknown third-party sites — they might bundle malware.
If you have the hardware, use the original CD or contact the seller for a clean download link.
If you can provide more details (e.g., what device it’s for, or a photo of the programmer board), I can give a more precise answer.

The Willar Programmer (often referred to as WLPRO or Willer Software) is a specialized utility used for burning .hex files onto 8051-series microcontrollers and EEPROM devices. While the software was originally designed for older versions of Windows, it can still be utilized on Windows 10 with specific configuration steps, particularly regarding USB drivers and COM port assignments. Core Functionality and Supported Devices
The Willar Programmer is primarily a "fusing" tool used alongside development environments like Keil C51. It supports a variety of chips, including: Atmel 89 Series: AT89C51, AT89C52, AT89S51, AT89S52. Winbond: W78E51, W78E52. SST: SST89C54, SST89C58. EEPROM: Various 24 and 93 series serial EEPROM ICs. Software Features
Auto-Detection: The software can automatically identify a connected programmer.
ZIF Socket Support: Designed to work with hardware featuring a 40-pin ZIF (Zero Insertion Force) socket for easy chip placement.
Integrated Verification: Built-in error checking, blank check, and program verification. Downloading the Software
Official distribution for this legacy tool is often through hardware vendors. Reliable download locations include:
Direct Drive Link: Some distributors provide a Google Drive link for the software.
Manufacturer Portals: NSK Electronics provides the software as an executable (.EXE) that can be run directly from your desktop.
Legacy Mirrors: Older versions like WLPRO V2.20 can be found on archives like EEWORLD. How to Use on Windows 10
To ensure the software functions correctly on Windows 10, follow these setup requirements:
Install USB-to-UART Drivers: Most Willar-compatible programmers use the CP2102 chip. You must download and install the Silicon Labs VCP Drivers for the device to be recognized. Assign COM Port:
Open Device Manager and locate "Silicon Labs CP210x USB to UART Bridge" under Ports (COM & LPT). Right-click, select Properties > Port Settings > Advanced.
Change the COM Port Number to a value below 5 (e.g., COM1, COM2, COM3, or COM4), as the software often fails to detect ports higher than 5 automatically.
Run the Software: The software does not typically require a full installation. Simply copy the .exe file to your desktop or C: drive and run it as an administrator. Flash the Hex File: Select your target device (e.g., AT89S52). Click Load to browse for your .hex file.
