PC doesn't accept License Server SSL certificate error
Last Updated 5 years ago

Some Workstations with missed windows updates may have the following error during a license activation process:


That error is caused by missed CA ssl certificate. Browsing to website and many other websites that use comodo/sectigo ssl certificate ( would also display the certificate error

To resolve that issue user should either:
- Install the latest Windows Updates
- Or manually install Sectigo CA certificate

In case of manual installations, the certificates should be downloaded directly from sectigo website

User should download and install these 2 certificates:
1) SHA-2 Root : USERTrust RSA Certification Authority
2) Sectigo RSA Domain Validation Secure Server CA [ Intermediate ]

"SHA-2 Root : USERTrust RSA Certification Authority" should be installed to "Trusted Root Certification Authorities" image

Sectigo RSA Domain Validation Secure Server CA [ Intermediate ] should be installed to "Intermediate Certification Authorities"
