One of the most frustrating errors encountered during the installation or upgrade of Kepware products (including KEPServerEX, ThingWorx Kepware Edition, or LinkMaster) is:

At its core, this is a security feature. KEPServerEX installers are digitally signed using a code-signing certificate to guarantee their authenticity and that they haven't been tampered with. For Windows to trust this signature, it must trace it back to a trusted Root Certificate Authority (CA) stored in your system's "Trusted Root Certification Authorities" store. When this chain of trust is broken, the installation stops. If you cannot use Windows Update, follow these

Kepware, like most modern software, signs its installers with a secure digital certificate. The Windows operating system uses a "Trusted Root Certification Authorities" store to verify these signatures. If your machine is not updated, or if it is running in a locked-down environment (no internet access), it may not recognize the certificate authority used by Kepware, resulting in this failure.

Newer Kepware installers are signed with certificates that rely on modern root authorities (such as DigiCert or Sectigo) that older OS versions do not recognize by default. This issue is not limited to a single version of KEPServerEX
