When I try to import a certificate, I get the following error: VBScript “Error in InstallResponse. Error Number 800B0109 ocurred.CertEnroll::InstallResponse: Se procesó correctamente una cadena de certificados, pero termina en un certificado de raíz no compatible con el proveedor de confianza. 0x800b0109 (-2146762487)” VBScript “Error in InstallResponse. Error Number 800B0109 ocurred.CertEnroll::InstallResponse: A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider. 0x800b0109 (-2146762487)” SOLUTION: Make sure that the root certificate is installed in the trusted root store. You also might have to make sure any intermediate certificates are installed in the intermediate store.
