Open the programming software you installed in Step 1.
The biggest hurdle to using a K150 on Windows 10 is the driver. The programmer uses a Prolific PL-2303 series chip (usually the PL-2303HX) to handle USB-to-serial communication. While these chips were a common, cost-effective solution, Microsoft and Prolific stopped supporting older, sometimes counterfeit, versions of these chips with modern Windows operating systems. When you plug in the K150, Windows 10 may either fail to detect it or display a yellow exclamation mark in the Device Manager with an "Error Code 10".
: To resolve this, you must manually install an older, "prolific" driver version (e.g., v3.2.0.0 from 2008) and prevent Windows from auto-updating it.
Search for "Prolific PL2303 Windows 10 driver rollback 3.3.2.102" or download an old PL2303 driver installer executable. k150 pic programmer software windows 10
Fix: Verify that the chip orientation in the ZIF socket matches the software diagram. Some chips require specific jumper configurations on the K150 board itself or must be shifted down the socket.
Consult the K150 socket diagram for your specific PIC chip architecture (e.g., 14-pin, 18-pin, or 40-pin). Place the chip into the Zero Insertion Force (ZIF) socket accordingly and lock the lever down.
Click the Program button (often represented by a chip icon with a red arrow). Open the programming software you installed in Step 1
Because newer Windows 10 drivers will reject the K150's serial chip, you must roll back to an older, compatible driver (specifically, a version from 2008 or earlier, like version 3.3.2.105).

Look up the specific pinout orientation for your PIC chip size inside the Micropro help files. While these chips were a common, cost-effective solution,
Unplug the programmer from your computer before running the installer.
You can find the software on Phipps Electronics or various electronics forums that host the Microbrn.exe package.
The official software bundled with the K150 is called (often referred to as DIY K150 software). The original executable files frequently crash, freeze, or fail to detect the COM port on 64-bit Windows 10 systems without compatibility adjustments. 2. Step-by-Step Guide to Install K150 Drivers on Windows 10
Click on Programmer → Test . If successful, the software will show "Target PIC found" (if a chip is inserted) or "Test Passed." 5. How to Program a PIC Chip
A common cause of failure is incorrectly inserting the PIC chip into the 40-pin ZIF (Zero Insertion Force) socket.
