This Microsoft documentation contains a list of standard certificate and certificate trust return values, including the CERT_E_MALFORMED error code 0x800B0108, which are found in the Winerror.h header file. While the Microsoft certificate store is expected to have all valid and acceptable certificates, it may not include a certificate for a particular piece of software on certain Windows systems, even when the software is up-to-date.

This can result in the aforementioned error code, indicating a missing or incorrectly configured certificate. To resolve this issue, a manual process to add certifications can be used through the Certificate Manager (certmgr.msc). To install individual certificates, they must first be downloaded from the appropriate source or publisher. This process allows for the installation of new certificates with the same or different keys, and also enables the exporting or importing of certificates. Instructions to import a certificate in Windows using Certificate Manager:

  • Press the Windows key + R on your keyboard to open the Run dialog box.
  • Type certmgr.msc and press Enter to open the Certificate Manager.

Troubleshoot Certificate Issues

  • In the Certificate Manager window, select the certificate store where you want to import the certificate. You can choose from the following options:

Personal: for certificates related to your user account

  • Right-click on the certificate store and select All Tasks > Import.
  • In the Certificate Import Wizard, click Next to begin the import process.
  • Click the Browse button and navigate to the location where the certificate file is stored.
  • Select the certificate file and click Open.
