I do not manage to install QGIS on my windows 10 machine using the osgeo4w installer.

During the installation I get this message: enter image description here

At the end of the installation I get this message: enter image description here

And when I subsequently try to run QGIS, I receive this message: enter image description here

Similar issue can be found in various fora, but none of them provides a conluding answer or did help me to solve the problem.

Any propositions?

  • do you have an anti-virus/firewall software installed? – Mapperz Oct 19 '18 at 16:58
  • possibly a duplicate of this question, I can't test this but a number of possible workarounds mentioned. – Steven Kay Oct 19 '18 at 21:39
  • @Mapperz: Yes, I do have an anti-virus/firewall software installed (Symantec Endpoint protection). And it seems as it was indeed the problem – Bushroot Oct 24 '18 at 7:22

This seems to be a known packaging issue, see

http://osgeo-org.1560.x6.nabble.com/unable-to-install-QGIS-with-OSGEO4W-on-windows-7-td5382341.html

As a workaround, I suggest to use an older standalone installer from http://download.osgeo.org/qgis/win64/ until the matter is fixed.

I managed finally to install QGIS as explained above. However, I am not able to backtrace the solution.

What I did, however, where (at least) the following steps:

  1. Remove the entire OSGeo4w directory
  2. Install QGIS with the standalonw installer (This worked)(https://qgis.org/en/site/forusers/download.html)
  3. Uninstall QGIS again
  4. Install QGIS with the OSGeo4w installer having the firewall/anti-virus disabled (This worked)
  5. Uninstall QGIS and install it again having the firewall/anti-virus enables (This worked)

There might be other minor changes that have enabled the proper installation. However, I do not remember them or might not even be aware of them.

As pointed out by @AndreasMüller, the reason might be simply that the package had been fixed in the meantime.

    I think, the package was fixed in the meantime, so your first attempt should also work (again) – Andreas Müller Oct 24 '18 at 8:45

You can try alternative installer by NextGIS (but only QGIS 2.18 now). Newer versions of libraries and nice autoupdate tool. You can install it in separate folder - NextGIS QGIS does not affect OSGEO4W installation.
