Top Download Mplab X Ide V535 | CONFIRMED · 2027 |
If you rely on legacy or third-party plugins (specific compilers, debugger bridges, or version control hooks), v5.35 is the safest bet. Versions 6.x frequently broke plugin APIs, forcing developers to wait months for updates. With v5.35, "what worked yesterday works today."
This version supports the vast majority of popular 8-bit PIC, 16-bit PIC, and 32-bit PIC32 microcontrollers, as well as AVR devices. Unless you are using a brand-new chip released in late 2020 or later, v5.35 will likely support your hardware.

MPLAB X IDE v5.35 is a critical version for many embedded developers because it was the final release to include the MPASM assembler. If you are working on legacy PIC microcontroller projects that rely on assembly language, this is the version you likely need. Key Highlights of v5.35
Final MPASM Support: Releases after v5.35 (v5.40 and later) transitioned to the 64-bit-only XC8 assembler, making v5.35 the "end of the line" for native MPASM support. Cross-Platform: Available for Windows, macOS, and Linux. top download mplab x ide v535
32-bit Capability: This version maintains compatibility with certain older 32-bit tools and plugins that were phased out in later 64-bit-only versions of the IDE. How to Download
Microchip does not host v5.35 on their main "current" download page. You must access it through the MPLAB X IDE Archives.
Navigate to the Archive: Go to the Microchip official archive page.
Locate the Version: Scroll down to the "MPLAB X IDE" section. If you rely on legacy or third-party plugins
Find v5.35: Look for the specific installers labeled for your operating system (e.g., MPLABX-v5.35-windows-installer.exe).
Install XC Compilers: Remember that the IDE itself does not include compilers. You will likely need to download a compatible version of the XC8, XC16, or XC32 compilers separately. Installation Tips
Side-by-Side Installation: You can install v5.35 alongside newer versions of MPLAB X. Just ensure you install it into a unique folder (e.g., C:\Microchip\MPLABX\v5.35) to avoid overwriting your current setup.
Java Requirements: v5.35 comes bundled with the necessary Java Runtime Environment (JRE), so you generally do not need to install Java manually. Report compiled based on public data as of 2026
macOS Warning: If you are on macOS Catalina or newer, v5.35 may struggle because it still contains 32-bit components, which modern macOS versions do not support.
Many low-cost programmers (like the PICkit 3, ICD 3, and even some clone devices) have spotty driver support in MPLAB X v6.x. Version v5.35 has mature, stable drivers for virtually every Microchip programmer released before 2020.
Quote from a top-rated DigiKey engineer: "We keep v5.35 on all our legacy support machines. If a customer from 2018 needs a firmware patch, v5.35 opens their old project without converting it to a new, incompatible format."
To truly understand why v5.35 is the top download, compare it head-to-head with v6.10 (latest as of this writing).
| Feature | MPLAB X v5.35 | MPLAB X v6.10+ | | :--- | :--- | :--- | | Project Format | Legacy (pre-DFP) | DFP-Forced | | XC8 Classic Mode | Native support | Requires manual XML tweaks | | PICkit 3 Support | Full, stable | Broken / Deprecated | | Windows 7 Support | Yes | No | | Startup Time | ~5-8 seconds | ~15-20 seconds | | Git Integration | Basic | Advanced (but buggy) | | Dark Theme | Yes (via Plugin) | Native | | Recommended RAM | 4 GB | 8 GB |
The Verdict: If you are developing for a modern AVR DA/DB or PIC32MZ with an ICD 4, use v6.x. If you are maintaining legacy products, teaching with PIC16F877A, or using affordable PICkit 3 clones, v5.35 is mandatory.
