    9. Conclusion

    There is no legitimate direct download of Siemens DIGSI 4.91 from a public URL. Access is strictly controlled through Siemens’ support portal with valid licensing credentials. Any website offering a standalone “DIGSI 4.91 download” without a license check is either outdated, fraudulent, or malicious. For existing users, follow the official Siemens support channel; for new users, purchase a license from an authorized Siemens distributor (though new sales of DIGSI 4 ceased in 2023).
