When accessing the Electronic Office of the FNMT , in the "Obtain/Renew your Digital Certificate" section, if the root certificate is not installed (AC ROOT- FNMT ) an error appears. To install the root certificate from the error page, click "Advanced options" and then click the "Access www.sede.fnmt.gob.es (not secure site)" link. This message may appear at each step on the FNMT page until you have the root certificate installed.
In the "Downloads" section at the bottom, click on "Root certificates of the FNMT " and click on the certificate "AC ROOT FNMT -RCM" to download it. It usually opens automatically, however, it can be located in the "Downloads" folder. Set a name ( FNMT for example) and press "OK" or "OK".
If everything is correct, the message " FNMT installed" will appear ( FNMT being the name we have assigned to it).
