Install otb 6.6.1 under qgis 2.18.24 under window 7

I had installed QGIS 2.18.24 on OSGeo4W, then the OTB stand-alone binary file. In QGIS, I manually entered the directory of

OTB Applications folder (C: \ Program Files \ QGIS 2.18.24 \ apps \ OTB-6.6.1-win32 \ lib \ otb \ applications) and

Command line folder (C: \ Program Files \ QGIS 2.18.24 \ apps \ OTB-6.6.1-win32 \ bin)

and I checked the “Enable” button.

But nothing happens when I close the Processing window and no OTB menu appears in the Processing toolbox.

How can I solve this problem?

Hi,
On windows I am not sure the spaces in the path will work, maybe try to install OTB in something like C:\otb\OTB-6.6.1-win32.
