Hi, it’s the self decryptor Axcrypt file that I’m trying to open, not the actual Axcrypt file. The More info shows nothing, it’s blank.
You said that
Unfortunately Microsoft has chosen to respect the fact that we’re digitally signed with a proper certificate.
Did you mean that Microsoft has chosen NOT to respect? I don’t think this applies here anyway because you don’t sign the self decryptor files?
I don’t trust Authenticode because it’s too easily tampered with. There is a version of Axcrypt on the internet which I haven’t installed because my antivirus says it’s not real. It has your certificate but a different date of signing when I compared it to the version of this website.
