MPLAB X IDE v5.35 is a legacy version (released circa 2019) of Microchip’s integrated development environment for PIC and AVR microcontrollers. No official portable version exists from Microchip Technology. Unofficial "portable" distributions carry significant security, stability, and licensing risks.

This report outlines the technical challenges of creating a portable version and provides the safest methodology if portability is strictly required.

If you are looking for a legacy version for an old project, please use the official Microchip archive to stay safe and legally compliant.

Whether you are a student, hobbyist, or professional developer, MPLAB X IDE v5.35 Portable is a great option for developing and debugging microcontroller-based applications.

Microchip does not provide an official portable version of MPLAB X IDE v5.35. The standard software requires a full installation to manage registry entries and system drivers for hardware debuggers like PICkit. 

However, you can still access and use this specific version through official archives or community workarounds.  1. Official Download for MPLAB X IDE v5.35 

Since v5.35 is an older release, it is hosted in the MPLAB Ecosystem Downloads Archive. 

Why v5.35? This version is widely sought after because it was the last version to support the MPASM assembler before Microchip transitioned to pic-as.

OS Support: It was the first 64-bit version of the IDE, improving performance on modern Windows, Linux, and macOS systems.  2. Potential "Portable" Workarounds 

While a native .zip portable build isn't available, users often achieve "portability" using these methods:  MPLAB® Ecosystem Downloads Archive | Microchip Technology

MPLAB X IDE v5.35 is a key release because it was the last version to include MPASM, the absolute assembler for 8-bit PIC microcontrollers. Key Feature: Integrated MPASM Support

The primary reason developers seek version 5.35 specifically is for its native support of legacy 8-bit assembly projects.

Legacy Compatibility: Supports absolute assembly code that newer versions (v5.40+) cannot compile due to the transition to the XC8 PIC Assembler.

One-Click Assembly: Directly integrates the MPASM toolchain for building, debugging, and programming PIC10, PIC12, and PIC16 devices.

Tool Pack Management: Introduced "Tool Packs" that allow you to update hardware debug tool firmware independently of the IDE version. Key Capabilities in v5.35

While the portable version is often community-made (as Microchip provides standard installers), the feature set remains robust:

Visual Call Graph: Navigate complex code structures with a graphical representation of function calls.

Data Visualizer: View real-time streaming data from your target microcontroller without extra hardware.

Multi-Configuration Projects: Manage different build settings (e.g., Debug vs. Release) within a single project file.

Cross-Platform Base: Built on the NetBeans platform, providing a feature-rich editor with code completion and hyperlink navigation.

💡 Note: Microchip provides official installers for Windows, Linux, and macOS on the MPLAB X IDE Downloads page. For older versions like v5.35, check the "Downloads Archive" section on that same site.

Getting Started with MPLAB X IDE v5.35 Portable For embedded developers and hobbyists, the MPLAB X IDE is the gold standard for developing applications for Microchip’s PIC and dsPIC microcontrollers. While modern versions have moved forward, many developers still specifically seek out v5.35.

Why? Because v5.35 was the final version to include the MPASM assembler. For legacy projects or developers who prefer the classic assembly workflow, this version is an absolute necessity. Making it portable adds a layer of convenience, allowing you to run your development environment from a USB drive or a cloud folder without a full system installation. Why Choose MPLAB X IDE v5.35?

Before diving into the download, it’s important to understand why this specific version remains so popular:

MPASM Support: As mentioned, newer versions (v5.40 and later) transitioned to the XC8 PIC Assembler. If you have older codebases written in MPASM, v5.35 is the last "safe" haven.

Stability: For many, v5.35 represents a "sweet spot" in performance and plugin compatibility before the IDE's architecture underwent significant changes.

Legacy Hardware: If you are working with older programmers or debuggers, v5.35 often provides better "out-of-the-box" driver support than the latest releases. The Benefits of a Portable Version

A "portable" version of MPLAB X IDE isn't officially distributed by Microchip, but developers often create them for several reasons:

No Registry Bloat: Keep your Windows registry clean by avoiding the standard installation process.

Zero Conflicts: Run v5.35 alongside the newest version of MPLAB X without them interfering with each other’s paths or Java runtimes.

Work Anywhere: Carry your entire toolchain—including compilers like XC8, XC16, or XC32—on a thumb drive. Just plug it in and start coding. How to Download and Setup MPLAB X IDE v5.35

Since Microchip typically offers the standard installer, here is how you can secure the files and make them portable: 1. Official Archive Download

Always start by downloading the original installer from the Microchip Archives. This ensures your files are genuine and free of malware. Navigate to the Microchip "Development Tools Archive." Scroll to the MPLAB X section. Locate and download the installer for v5.35. 2. Creating the Portable Environment

To make the installation portable, you can use a "sandbox" or "extraction" method:

Install to a specific folder: Instead of C:\Program Files, install the IDE to a dedicated folder like C:\MPLAB_Portable.

Redirect User Data: By default, MPLAB X saves settings in your Windows User profile. To make it truly portable, you can modify the mplab_ide.conf file (found in the etc folder of your installation) to point the userdir and cachedir to relative paths within your portable folder. Important Considerations

Java Runtime (JRE): MPLAB X v5.35 comes bundled with its own JRE. Ensure you don't delete this folder, as the IDE relies on it to run.

Compilers: Remember that the IDE is just the editor. You will also need to download and "portabilize" the XC Compilers (XC8, XC16, etc.) to have a fully functional build environment.

Drivers: While the IDE can be portable, hardware drivers (for the PICkit or ICD) usually require a one-time installation on the host machine to recognize the USB hardware. Conclusion

Downloading MPLAB X IDE v5.35 is a smart move for anyone maintaining legacy assembly code or seeking a stable, familiar environment. By setting it up as a portable application, you gain the flexibility to code on any machine without the headache of a full re-installation.
