Help with snappy installation

snap
1

Hi,

I have

  1. 64-bit Windows 10 on an Intel 64-bit laptop.
  2. 64-bit Python (version 2.7.14) [MSC v.1500 64 bit (AMD64)] on win32]
  3. 64-bit SNAP 6 (all toolboxes)

My problem:
I cannot configure snappy because it keeps saying that there is a runtime error saying that it “Can’t load IA 32-bit .dll on a AMD 64-bit platform”.

My question:
I have not yet install GDAL and Mapserver as of yet. Should I install the 64-bit Gdal prior to configuration?

Many many thanks in advance.

Here is the full error message:

p.s. I also tried configuring SNAPPY with 32-bit SNAP 6 and 32-bit python. This is the error message I get:

Are you sure about the Python version? Is it 64Bit?
Maybe you have tow installations and snappy uses the wrong one?
You can check the settings in <USERHOME>\.snap\snap-python\snappy.properties
There is the path to the python executable specified.

Probably it is best if you remove the gdal modules. In the following thread it is explained how to do it.
