Having trouble upgrading from QGIS 1.8, which ran just fine, to QGIS 2.8.

I'm running 64-bit Windows 7. After uninstalling QGIS 1.8, I've been trying for several days to install the 32-bit version of the QGIS 2.8 Standalone Installer.

The installer runs, but there's no program to start. The Start Menu folder is empty, and there is no qgis.bat in the directory that I installed to (C:\qgis). Trying to run qgis-bin.exe throws an error telling me that qgis_core.dll can't be found. The postinstall.log file has 15 instances of the error "System cannot find the path specified."

Any ideas?

  • It might help if you add the part of postinstall.log around where the first error message is stated. – AndreJ Apr 4 '15 at 11:07
  • I am having the same problem, no answers to solve it? – user52678 May 26 '15 at 15:56

  • I have this too. Weird that there is no answer to it. – Mike Wise Jun 16 '15 at 18:11

From my experience, there are 2 possibilities:

  1. Have you tried to format your computer?

  2. Have your tried to disable your anti-virus for the installation?

In the company I work, 4 computers installed it with no problems, but other 2 had exactly the same issues you described (running on 64-bit Windows 7).

We had to format these 2 computers, and after that the installation had no problems.

If you are in a network (like I am, at work), try installing with "Run as administrator" or calling the network manager to give your computer full permission to install softwares.

We didn't understand the problem though, maybe some messed up Microsoft's .NET Framework package.

Another thing we noticed, before we formatted the computers, the installation was too fast (it finished, but too fast), so I think something was blocking part of the installation without the installer noticing it (resulting in missing files like the qgis_core.dll).
