The "keep ratio" is not saved after a resize

[mulanee]

it works here, are you use that you have rights to write xnview.ini?

I am admin so I have the rights.
I tried to edit/modify/save the xnview.ini without any problem

By forcing the option in the .ini it works but this is just a workaround

Finally I found out.

In parameter/system integration/integration, it has to be in register, not in ini in the folder
