Starting with version 5.40, Microchip transitioned the entire MPLAB X ecosystem exclusively to 64-bit architectures. For engineers who rely on 32-bit Windows or legacy Linux laboratory machines, v5.35 is the absolute end of the line.
Locate and open the file named using a text editor (like Notepad++). Look for the line containing default_userdir .
While the IDE itself requires installation due to its reliance on system drivers and registry entries, you can achieve to move work between different machines:
If you are working with PIC16 or PIC18, I can help you find the best XC8 compiler version to pair with v5.35. download mplab x ide v535 portable
Since no official portable version exists, the first step is to obtain the standard installer directly from Microchip. You can find it in their official archive.
Newer is not always better in embedded development. Developers specifically seek out version 5.35 for several critical reasons:
Technology moves forward, but in embedded engineering, stability often trumps novelty. Version 5.35 remains highly sought after for several critical reasons: Starting with version 5
Modify it to point to a local relative directory. Change it to: netbeans_default_userdir="$default_userdir_root/.mplab_ide/dev/v5.35/userdir"
A fully portable application operates independently, storing all its settings and temporary files within its own directory (e.g., on a USB drive) and leaving no trace on the host computer. Because MPLAB X IDE v5.35 is a complex Java-based application that integrates with system drivers for hardware programmers (like PICkit), a truly 100% portable version is not feasible. However, a configuration is possible.
For older PIC16, PIC18, or PIC32 devices, v5.35 offers mature support without the bloat of newer, unsupported devices. Understanding "Portable" in the Context of MPLAB X Look for the line containing default_userdir
Save the file. Now, all preferences, window layouts, and recent projects remain strictly on your portable drive. Integrating Essential Compilers and Toolchains
If you need to use the IDE on a computer where you cannot install software (e.g., a restricted lab or library PC), the MPLAB Xpress Cloud-Based IDE is the official solution. Microchip Technology
