Kepware The Installer Was Unable To Find Required Root Certificates Exclusive File

: The installer executable is signed using trusted Certificate Authorities (CAs) like Sectigo or Entrust . If the operating system lacks these specific updated public root keys, it rejects the installer as untrusted software. Step-by-Step Resolution Strategies

This error typically halts the installation process immediately, preventing any Kepware product from being installed. Below is an exclusive breakdown of why this happens and how to resolve it permanently.

Then:

Choose and click Browse . Select Trusted Root Certification Authorities and click OK . Click Next , then click Finish to complete the import.

You need the DigiCert Trusted Root Authority certificate, as modern Kepware installers often use DigiCert. : The installer executable is signed using trusted

Run Windows Update to ensure all security certificates are current. Restart the installation.

F. Reinstall or repair Windows Root Certificate Program Below is an exclusive breakdown of why this

The "required root certificates" error in Kepware is not a bug, but rather a feature of modern cybersecurity clashing with outdated system trust stores. It's a strict security mechanism triggered by a PKI (Public Key Infrastructure) trust chain断裂 (breaking).

Such entries confirm the installer is failing to find the necessary root certificates from authorities like GlobalSign, VeriSign, or Microsoft. Click Next , then click Finish to complete the import

Kepware installers use strict file signature validation to ensure malware or corruption hasn't modified the industrial drivers.

Resolving the “exclusive root certificate” failure is a lesson in bridging security silos. The immediate fix involves manually updating the Windows root certificate store. On an online machine, simply running Windows Update or installing the “Update for Root Certificates” (KB931125) often suffices. For air-gapped systems, an administrator must export the required root certificate from an internet-connected machine (by examining the digital signature of the Kepware executable or its installer) and then import it into the offline machine’s Trusted Root store using the Microsoft Management Console (MMC) Certificates snap-in. A more subtle solution involves temporarily disabling certain antivirus or application control software that intercepts certificate validation. Some hardened security suites inject their own roots or block access to the default Windows store, causing the Kepware installer to see an empty or altered store. Ultimately, the error forces a choice: relax restrictive security policies just enough to allow the legitimate root, or accept that modern industrial software requires periodic trust maintenance.
