[Osgeo4w-trac] { EXTERN } Re: [osgeo4w-dev] [osgeo4w] #888: Detection of QGIS install (via OSGeo4W installer) for mass deployment

[Andreas Müller]

When installing with the setup.exe/network installer you'll have installed.db in etc/setup with all version numbers and it's probably the last file written when installing. But I'm not sure if this file is available with the msi installer.
