Thank you for accepting the issue,
I'd like to say that Workaround might be good for some cases, but thats not my case.
As far as I see certificate is embedded into executable as overlay, maybe thats the reason of mis-behavior?

Anyway, digital certs removal as an option is already present, so it might be done for sure by hands,
but this issue goal is to automatically take into account the fact of presence of digital cert in case when one is adding new import...
is it doable?
I tried some other tools - all are corrupting cert in this scenario, so that might be a magic feature successfully performed by this grand tool

PS I understand that purpose of cert is to ensure the input file is genuine, but... in some cases this is still an option to leave it as is.
so ideally would be to ask user in twofold-
a) remove cert
b) leave it and
do the job
