The issue at hand with windows and some anti-virus apps is that they block any app that is not code-signed by a trustworthy code signing certificate (at least until sufficient crowd-sourced evidence has been collected that a not-yet trusted app would be safe to use).
For the 'trustworthy code signing' you need a code-signing certificate, which is much like the TLS certificates, but meant for code-signing instead of server-authentication (the intended usage is part of a certificate)
Like the TLS-certificates they exist in flavors 'standard' and 'extended validation' for a variety of prices, but unlike Let's Encrypt for TLS certificates there is no for-free code-signing cert (as code-signing certificates require a level of validation of the requesting organisation and requester, whereas the domain-validated TLS certificates need only proof that requester is in control of the domain name(s) for which the cert is requested and makes no assertion on who/which organisation is behind a certain domainname).
