Regarding of the discussion: "Can't sign add-in with ESRISignAddIn.exe version 10.2.2.3552 (solved)"
The windows update:
doesn't give only a problem with the signing of an add-in but also that the signature isn't valid.
After install this update, our add-in gives this error message:
But it was signed by a valid certificate!
This is an important problem for us because we can not ask our customers to ignore some windows updates.
I hope, someone has a better solution for this problem.
Thanks in advance,
