I´ve been working with QGIS 2.4 since two months ago. After doing some changes in my computer, I think I've lost something important for running QGIS 2.4

The message is:

qgis.exe - System error.

The program can´t start because qgis-core.dll is missing from your computer. Try reinstalling the program to fix the problem

I reinstalled the 2.4 32 and 64, the 2.2 version and the problem is still there. I can't open QGIS. It shows the first window and crashes. The QGIS browser works fine....

This is the path of my computer:

C:\Program Files\Gimp-2.8\bin;C:\Python34\;C:\Python34\Scripts;C:\Python34\Lib\site-packages;C:\Program Files (x86)\Intel\iCLS Client\;C:\Program Files\Intel\iCLS Client\;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\Hewlett-Packard\SimplePass\;C:\Program Files (x86)\Windows Live\Shared;C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static;C:\Program Files\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\IPT

and the python path is:

C:\Python34\Lib;C:\Python34\DLLs;C:\Python34\Lib\lib-tk;C:\Python34\Scripts;C:\Python34\Lib\site-packages;C:\Python34\projects

I don´t know what to do to fix the problem and I can´t find anything on the web.

  • Does it work if you rename the C:/Python34 folder? QGIS needs its own Python 2.7 to run. – AndreJ Aug 25 '14 at 15:40
  • How can I work with both versions ? – kamome Aug 25 '14 at 16:13

    If my tip works, you would have to exchange the PYTHONPATH variable when you start QGIS, and restore it after quitting. QGIS is called with qgis.bat. That batch file changes the PATH and PYTHONHOME variable to avoid conflicts, but not PYTHONPATH. – AndreJ Aug 25 '14 at 17:31
  • Show the PYTHONPATH with and without the changes. – kamome Aug 26 '14 at 7:12
  • PYTHONPATH is not changed by QGIS, but maybe used. – AndreJ Aug 26 '14 at 9:18
