You may receive the following warning message when trying to install BarTender. This is usually due to the root certificates being outdated on the system where BarTender is installed.




To prevent this error from occurring, please try the following.

  1. Make sure Windows is up to date.
  2. Check if the certificate is present by running the following PowerShell command:
        Get-ChildItem “cert:\” -Recurse | Where-Object { $_.Thumbprint -eq “ddfb16cd4931c973a2037d3fc83a4d7d775d05e4” } | Format-List
  3. Run the following PowerShell command as Administrator to update the root CA certificates on the system, which should update the Digicert G4 root CA and fix the issue.
        certutil -generateSSTFromWU roots.sst
        $file=Get-ChildItem -Path roots.sst
        $file | Import-Certificate -CertStoreLocation Cert:\LocalMachine\Root
