Issue Summary

BLAZE software packages are digitally signed and verified before installation. If the required DigiCert root certificate is missing, expired, or unavailable on the customer’s PC, the installation fails during signature verification.

When this issue occurs, the BLAZE Client installer may silently fail or display an error. Error logs may contain messages such as:

• WinVerifyTrust failed
   
• Package digital signature verification failed. Installation aborted.
   
• ImproperRootCertificate

   NOTE: If the PC has no internet access, download the certificate file 
   on another PC and transfer it via USB.
