Bug report #16892

Updated by Jürgen Fischer about 4 years ago

For days now, Launching QGIS nightly from osgeo4w 64bit result in a "Processing couldn't load" error with
_ImportError: No module named expat; use SimpleXMLTreeBuilder instead_ message
During installation process I checked the libraries and there's an expat package at version 2.1.0-1 enabled.
Any Ideas?

Below the stacktrace:
