“ImportError: DLL load failed” when trying to use GDAL on Windows 7 64bit (Python 3.4.4 32bit)

Question

What I would like to do

Installing GDAL on Windows7 64bit

Precondition

• Python 3.4.4 32bit (32 bit is necessary to combine other software with GDAL) installed
• Visual Studio C++2010 32bit and 64bit Redistributable package installed

• GDAL is downloaded from the following site:

  • http://download.gisinternals.com/sdk/downloads/release-1600-gdal-2-2-3-mapserver-7-0-7/mapserver-7.0.7-1600-core.msi
  • http://download.gisinternals.com/sdk/downloads/release-1600-gdal-2-2-3-mapserver-7-0-7/GDAL-2.2.3.win32-py3.4.msi

As for environment variables, I set the following three settings:

• PATH
• GDAL_DATA
• GDAL_DRIVER_PATH

Answer 1

I solved my problem. GDAL does not work because GDAL refers dll file which other software made before.(The dll file other software made is same name as GDAL's dll). So, I fixed the dll path appropriately.Thanks.
