The administrator rights were mainly necessary to install the MS runtimes - and earlier we used a number of them, for a lot of packages didn't keep track of which required which, therefore didn't surely know which one could be left out. The older ones and the newer one don't have to be installed, but inbetween there where some in between did. Now everything is built with one compiler (except GRASS) and requires only one runtime, which doesn't require installation - just dropping the DLLs in is enough. But conflicting DLLs in system32 might still be an issue. The installer only addresses a few common ones like openssl and opencl - and if you need those, you'll not get around running the installer elevated. QGIS itself is less vulnerable to such issues as it uses AddDllDirectory/SetDefaultDllDirectories to avoid system32's otherwise prominent role. Thinking of it, we might need to add that to crssync too - it inherited a lot of indirect dependencies when GDAL/OGR became a core provider. Jürgen -- Jürgen E.
