How to setup FastCGI setting of IIS with GDAL libs

I set up a django website via IIS manager, which is working fine, then I add a function by using GDAL libs and the function is working fine. And also it is fine if I run this website by using CMD with this command

python path\manage.py runserver 8000

But it cannot run via IIS

I got error is DLL load failed: The specified module could not be found., which from from osgeo import gdal, osr

My guess is I need to set environment variables to FastCGI Settings of IIS

I set these to environment variables collections but does not work.

GDAL_DATA C:\Program Files (x86)\GDAL\gdal-data

GDAL_DRIVER_PATH C:\Program Files (x86)\GDAL\gdalplugins

Any help would be appreciated
