If the private key is missing, this could mean:
  1. The certificate is not being installed on the same server that generated the CSR.
  2. The pending request was deleted from IIS.
  3. The certificate was installed through the Certificate Import Wizard rather than through IIS.



You can follow the steps to resolve the issue.
