AATL certificate not approved

[Guest]

I have this certificate:

It is an AATL certificate so it should be accepted automatically...

But for some reasons on some PCs it does not do this:

I'll translate: at least one signature is problematic

On that PC

I am using the most recent version of adobe

I tried updating the trusted AATL certificates manually

I tried updating the EUTL certificates manually.

But still the signature stays problematic.

Is there something wrong with the global sign root certificate??

Hi tomp11142991,

Sorry for the delay in response.

Is there already a signature applied to the file? Multiple signatures in a PDF - without invalidating the previous ones

Would you let us know the version of Acrobat/Reader installed? If you already have received a resolution to this issue, would you please share your findings on this thread, if possible.
