Archer NX200 - ISP file upgrade failing with error 71212
Hello,
I am based in Italy and I have an Archer NX200.
Firmware version: 1.2.0 3.0.0 v60e0.0 Build 250725 Rel.73467n
ISP version: 25070803
I noticed that an update for the ISP file is available at this link, but when I try to install it, I get an error with code 71212 (as shown in the screenshot below).

I tried to install directly the isp_upgrade_NX1.zip with no success.
Then, I unzipped it and tried to install the two resulting files (attachment and NetIspInfo) alternatively, getting the very same error messages for all the three tentatives.
Could you please help me understanding what I am doing wrong?
Thank you in advance,
Francesco
