Sidenote: The MSIs weren't relying on big tech. The download came from OSUOSL's and OSGeo's download servers and norbit.de - with download.qgis.org randomly redirecting to one of the three. > We are wondering if the datum shift files could be split out from the main > installer and fetched as an optional extra?

Is anyone able to help with this? The dependency of proj to proj-data was dropped in OSGeo4W (which is what brought proj-data into the installer) and a new package was introduced called qgis-full-grids, that depends on qgis-full (which is what the default installer packages) and proj-data. qgis-full also includes proprietary extensions (oracle, sql server, ecw, mrsid, filegdb and hdf5), so basing the "lean" installer on qgis-full-free would be an option too and would make it even smaller (but may force people to download the "fat" package). The idea is to create MSIs for qgis-full as usual (but now without the grids) and qgis-full-grids including the grids and make both available. The MSIs also ship the OSGeo4W installer so installing proj-data afterwards would still be possible (although that requires admin rights like the MSI). BTW the MSIs are currently signed with an expired certificate - OSGeo (ie. Mike Smith) renewed the certificate, but it's somehow tied to a hardware key now and Mike is still figuring out how to get if off there to make it available. Jürgen -- Jürgen E.
