Since no official portable version exists, you must start with the standard installer. Microchip maintains an archive of older versions.
A: Yes. Microchip allows free download and use of MPLAB X IDE for development. No license fee. XC8 compilers have a free mode (optimization limited) and paid PRO mode.

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 download mplab x ide v535 portable
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.
While there is no "official" standalone portable version of MPLAB X IDE v5.35, users often seek it to maintain stability for legacy projects or to run the environment from a USB drive without a standard installation. MPLAB X IDE is an open-source, NetBeans-based platform used to develop applications for Microchip microcontrollers, including 8-bit PIC and AVR, 16-bit, and 32-bit SAM/PIC32 devices. The Significance of Version 5.35 Since no official portable version exists, you must
Version 5.35 is a critical "legacy" release for many embedded developers because it is the final version to include the MPLAB ASM30 Assembler. Subsequent versions transitioned more heavily toward XC compilers, making v5.35 essential for maintaining older assembly projects. Additionally, later versions (starting from v6.25) dropped support for popular 3rd-generation tools like the PICkit 3 and ICD 3, further cementing v5.35's value for users with older hardware. Accessing the Version 5.35 Download
To obtain the standard installer for this specific version, you must visit the official MPLAB X Ecosystem Downloads Archive.
Locating the File: Scroll through the archive to find "MPLAB X IDE v5.35."
Operating Systems: Official installers are available for Windows, Linux, and macOS.
Related Tools: You will also likely need the MPLAB XC Compilers (e.g., XC8, XC16, or XC32) to compile C code, as the IDE itself is primarily a management and debugging environment.
Before you click "download" anywhere, verify:
Remember: Version 5.35 is no longer officially supported by Microchip for new device families (e.g., PIC64, newer AVR Dx). If you need modern chips, you must use v6.00+.
Yes – for legacy maintenance. If you support a product that was designed in 2019-2021 and cannot tolerate toolchain changes, creating a portable v5.35 environment is a smart move. It allows you to freeze the development environment on a USB stick, replicate it across multiple PCs, and avoid the hassle of re-installing drivers on every machine.
No – for new designs. For new projects, embrace MPLAB X v6.20+ with its modern Git integration, better C++17 support, and native dark theme.
Microchip Technology does not offer a portable version of MPLAB X IDE. The official downloads are .exe installers for Windows, .dmg for macOS, and .sh/.deb for Linux. These installers are designed to: Important notes
Therefore, any website promising a direct "Portable MPLAB X v5.35.exe" is almost certainly malware, adware, or a repackaged version that will break on update.
Do not download pre-packaged "portable" versions from unknown forums or torrent sites. They often contain keyloggers or cryptocurrency miners.
