Can you use QGIS with an ECW library?
Long story short: the latest version of this libraries (that allow to read, but not write ECWs) are free of charge but are not redistributable, this means that cannot be shipped together with software packages like QGIS.
Are there any old libraries that support ECW?
The good news is that are still available old libraries from the times when the ECW format was owned (and developed) by a company that used a more permissive license. So: go inside “c:\\program files\\gdal” and “c:\\program files\\gdal\\gdalplugins” and pick two .dlls libecwj2.dll and gdal_ECW_JP2ECW.dll
