Florin,
Thank you for your reply.
I did find the file you mentionned but I still am confused about the exact location.
Probably my mistake but I was under the impression that I should be looking for that file on the main PC where I installed FSX/P3D.
That is not the case because I only found that file on the client PC where ASN is installed.
And then, not in the location you provided, but in appdata/roaming/hifi/ASNFSX/weather...
(I was missing the 'roaming' in the path)
Later today, I am going to try it out.
Thanks for the reply
Luc
