Fix: Check your COM port settings in the software. This happens when the software tries to communicate with a COM port that does not belong to the K150.
Given the K150's limitations, many developers opt for more modern and well-supported programmers on Windows 10.
In 2026, getting a clone K150 to work is a challenge. If that sounds like you, and you're on a very tight budget, the K150 can be a viable tool.
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.
Here’s the most common method the community uses to get the K150 working: k150 pic programmer software windows 10
Choose the older version from the list (Version 3.3.2.102 [2008] or similar) and click Next . The yellow triangle should disappear.
The K150 ships with a mini-CD containing software and drivers designed for Windows 98/XP. On Windows 10:
: Open Device Manager , right-click the "Prolific USB-to-Serial" entry, select Uninstall device , and check the box to Delete the driver software for this device .
The most common software is Microbrn.exe , often found on the mini-CD that comes with the programmer. Be extremely careful with this. Antivirus and security software frequently flag it as a Trojan. While this is often a (the software's outdated methods of directly accessing hardware can trigger alarms), you should never completely ignore such warnings. If you choose to use it, download it from a source that has been vetted by other users, such as the "diy k150 v150807" version. For safety, some experts recommend running it in a "sandboxed" environment, like a dedicated virtual machine without internet access. Fix: Check your COM port settings in the software
Most budget K150 clones utilize a counterfeit or older chip.
The K150 is one of the most affordable and widely available PIC microcontroller programmers on the market. For many hobbyists and students, it’s the gateway into embedded development. However, its age means it has a complicated relationship with modern operating systems. This guide will explore its compatibility and how to get it working on Windows 10, as well as offer some suggestions for modern alternatives.
Install the older driver package on your system. Plug in the K150: Connect the device to a USB port.
(often a version intended for Windows Vista or early Windows 7). Manual Override In 2026, getting a clone K150 to work is a challenge
Follow the on-screen prompts to complete the installation framework.
Lift the lever on the Textool ZIF socket. Place your PIC chip into the socket, aligning Pin 1 with the top of the lever side according to the diagram displayed inside the Microbrn software window. Lower the lever to lock it.
Before placing your PIC into the Zero Insertion Force (ZIF) socket, look at the graphical pinout indicator inside the Micropro software interface.
