I've got a problem using qGIS. Always when I try to launch the programme with the desktop icon, nothing happens. I also checked the Task Manager and it doesn't show any process running regarding qGIS.


@yalestar: The target field shows this: "C:\Program Files\Quantum GIS Lisboa\bin\nircmd.exe" exec hide "C:\Program Files\Quantum GIS Lisboa\bin\qgis.bat"

@Sven: I don't think that's the case, as I don't get any error message, but I'll give it try.


@Underdark: I had Microsoft C++ 2008 already installed, so I launched the installer and selected to repair it. However, qGIS still isn't launching.

@Sven: I've tried your soulution, but qGIS still isn't launching.

@mapoholic: Nope, I'm using Vista 32-bit.


@Andre Joost: I've tried to launch it manually, but then I get an error message telling me, that qgis.bat couldn't be found. I don't have any .qgs files on my PC, so I can't test it.


@M P: Thank you for the help. :) However, I can't find qgis.bat in the bin folder. But there's a file there called 'qgis.bat.tmpl'.

Assuming you're using Windows, if you right-click the icon and select 'Properties', what is the value of the 'Target' field? Does that file exist? –  yalestar Aug 6 '12 at 20:37
    
you are not using 64bit windows by any chance? –  mapoholic Aug 7 '12 at 9:52

Have you tried to start the qgis.bat manually? If you start it in cmd box, you might be able to read error messages. What happens if you double-click a .qgs project file? –  Andre Joost Aug 7 '12 at 15:27
    
I'm afraid your Qgis installation is totally broken. Please uninstall and try again. –  Andre Joost Aug 10 '12 at 19:31

Usually the reason for this is a missing Microsoft Visual C++ 2008 Redistributable Package (x86). Install and try again.

A crumb for those in need: At least for my win7 pro x64 box I had both x64 and x32 versions of Microsoft Visual C++ 2008 Redistributable Package installed (and fully updated) and still QGIS failed to start. Can now start it with "C:\Program Files (x86)\QGIS Valmiera\bin\nircmd.exe\qgis.bat", but still not sure why the default install program links don't work. (And I've installed it twice so far.) Thanks underdark! –  Eliptical view Apr 6 at 5:06

I had the same problem...I resolved it by doing the following: - Upon locating qgis.bat, right click and go to edit mode. - add PATH %systemroot%\system32; %systemroot%; %systemroot%\system32\wbem after @echo off - Save - Retry launching qGIS.

I don't know why, but think i had this problem due to some system .dll files that were already on my machine and may have conflicted with those belonging to qgis.

Good luck
