You can download a portable version of QGis 3.44.0 from this link<\/a><\/p>\n\n\n\n

The compressed file is 1.2 GB. Once decompressed, it will occupy 2.91 GB on disk.<\/p>\n\n\n\n

What is a portable application?<\/h2>\n\n\n\n
A portable application (or portable software) is a computer program characterized by its portability, i.e. its ability to run in different execution environments. It requires no prior installation, does not depend on external components, and does not cause any lasting modification to the system through its operation.
These applications are useful for working on a computer whose security policy does not allow installations, or for avoiding lasting modifications to a computer used temporarily. The application can then be used from a removable storage device such as a USB key.<\/p>\n\n\n\n
Instructions for use<\/h2>\n\n\n\n
Download the .7z file.<\/p>\n\n\n\n
Unzip it onto the desired medium: USB key, external disk, PC directory. The only requirement is that you have read and write access to the directory created: \/QGIS 3.44.0<\/em><\/strong><\/p>\n\n\n\n
To run QGis, double-click on the file \\launch_qgis_portable.bat<\/em><\/strong><\/em><\/strong><\/p>\n\n\n\n
That’s all there is to it!<\/strong><\/p>\n\n\n\n
$\"\"$ <\/a><\/figure>\n\n\n\n
Plugin installation<\/h2>\n\n\n\n
The downloaded version works in the same way as the installer version: the plug-ins are installed in a directory under the key: \\QGIS3.44.0\\QGIS_PROFILE<\/em><\/strong><\/p>\n\n\n\n
If you want to take the plug-ins with you from your PC, as well as all QGis customizations, you’ll need to copy the C:\\Users\\user_name\\AppData\\Roaming\\QGIS\\QGIS3\\profiles<\/em><\/strong> directory into this key directory: \\QGIS3.44.0\\QGIS_PROFILE\\profiles<\/strong><\/p>\n\n\n\n

🆕 May 2026 : \u201cWhat\u2019s new in this update\u201d<\/h1>\n\n\n\n
Major improvements in this release<\/h2>\n\n\n\n
This updated version of QGIS Portable 3.44 introduces several important fixes and enhancements to improve stability, compatibility, and usability in real-world environments.<\/p>\n\n\n\n
\n\n\n\n
1. Python environment fixes (critical)<\/h2>\n\n\n\n
Several issues affecting Python initialization have been resolved:<\/p>\n\n\n\n
\n
Fixed incorrect handling of Windows paths (e.g. `\\a<\/code>, \\t<\/code> interpreted as special characters)<\/li>\n\n\n\n`
Resolved errors such as:\n\nModuleNotFoundError: No module named 'qgis'<\/code><\/li>\n\n\n\n SIP module loading failures<\/li>\n<\/ul>\n<\/li>\n\n\n\n Improved compatibility with systems where multiple QGIS versions are installed<\/li>\n<\/ul>\n\n\n\n👉 Result: Python support is now fully functional in portable mode.<\/p>\n\n\n\n \n\n\n\n 2. Improved environment detection<\/h2>\n\n\n\nThe launcher has been updated to correctly initialize:<\/p>\n\n\n\n \nQGIS internal paths (prefix, plugins, resources)<\/li>\n\n\n\n environment variables required by GDAL, GRASS and Qt<\/li>\n<\/ul>\n\n\n\n👉 Result:<\/p>\n\n\n\n \nmore reliable startup<\/li>\n\n\n\n no hidden misconfigurations<\/li>\n\n\n\n better cross-machine compatibility<\/li>\n<\/ul>\n\n\n\n \n\n\n\n3. Authentication system now supported<\/h2>\n\n\n\nThe QGIS authentication system is now properly initialized in portable mode.<\/p>\n\n\n\n Previously, users could encounter the message:<\/p>\n\n\n\n Authentication System: DISABLED<\/code><\/pre>\n\n\n\nThis has been fixed by:<\/p>\n\n\n\n \ncorrectly configuring the QGIS profile environment<\/li>\n\n\n\n ensuring required paths are detected<\/li>\n\n\n\n enabling authentication database initialization<\/li>\n<\/ul>\n\n\n\n👉 Result:<\/p>\n\n\n\n \nsecure connections (PostgreSQL, WMS, APIs) now work<\/li>\n\n\n\n authentication settings accessible in QGIS<\/li>\n<\/ul>\n\n\n\n \n\n\n\n4. Fully isolated portable environment<\/h2>\n\n\n\nThe portable setup is now more robust and self-contained:<\/p>\n\n\n\n \nno interference with system-installed QGIS versions<\/li>\n\n\n\n isolated Python environment<\/li>\n\n\n\n dedicated user profile<\/li>\n\n\n\n consistent behavior across machines<\/li>\n<\/ul>\n\n\n\n \n\n\n\n5. Improved launcher script<\/h2>\n\n\n\nThe launch_qgis_portable.bat<\/code> script has been significantly improved:<\/p>\n\n\n\n \nbetter handling of paths with spaces<\/li>\n\n\n\n safer environment variable configuration<\/li>\n\n\n\n improved reliability in enterprise environments<\/li>\n<\/ul>\n\n\n\n \n\n\n\nTested environments<\/h1>\n\n\n\nThis version has been tested on:<\/p>\n\n\n\n \nWindows 10 \/ 11<\/li>\n\n\n\n systems with multiple QGIS installations (MSI + portable)<\/li>\n\n\n\n environments with restricted permissions<\/li>\n<\/ul>\n\n\n\n \n\n\n\n📥 Download<\/h1>\n\n\n\n👉 Download link<\/a><\/p>\n\n\n\n \n\n\n\n⚠️ Important notes<\/h1>\n\n\n\n\nIt is still recommended to extract the portable version to a simple path (e.g. C:\\QGIS_Portable<\/code>) for best compatibility.<\/li>\n\n\n\n On first launch, QGIS may initialize its profile and authentication system.<\/li>\n<\/ul>\n\n\n\n \n","protected":false},"excerpt":{"rendered":"You can download a portable version of QGis 3.44.0 from this link The compressed file is 1.2 GB.
