Qgis cannot be opened after installation


The reason why the executable caught an error is because of the way Microsoft Windows do its search or specifically the operating system’s search order to find the needed DLL for an executable. First, it will search in the installation folder of the application or where the executable is located. Next, it will search in “C:WINDOWSsystem32”.

And only after it finishes searching in this folder, it will search PATH, the system variable used in the operating system. Microsoft Windows will search the values stored in the PATH variable to find the required DLL file for the executable. In other country, older QT DLLs are placed in the “C:WINDOWSsystem32” folder. Normally, renaming these old QT DLLs to something else will stop the services.

See if this fixes the problem. Another way of fixing it without renaming the older QT DLLs is to copy the DLLs “QtCore4.dll” and “QtGui4.dll” to the folder where “qgis.exe” is located. This should fix the problem.
