At its core, a root certificate is the ultimate anchor of trust in the public key infrastructure (PKI). Issued by a trusted Certificate Authority (CA) such as DigiCert, GlobalSign, or Let’s Encrypt, the root certificate is self-signed and stored in a protected “Trusted Root Certification Authorities” store within the operating system. When Kepware—or any modern application—attempts to establish a secure HTTPS connection for licensing, updates, or IoT Gateway communication, it checks the server’s certificate against this local root store. If the chain of trust leads back to a missing or untrusted root, the connection fails. The word “exclusive” in the error message is particularly telling: it implies that the installer is looking for a specific , non-generic root certificate, likely tied to Kepware’s code-signing or a proprietary communication component (such as the ThingWorx or IoT Gateway add-on). Without that precise root, the installer refuses to proceed, prioritizing security over functionality.
