Installing an MSCAPI Credential
MSCAPI certificates are stored in the Microsoft Windows certificate database. This storage area is accessible through the Internet Explorer Tools → Internet Options → Content menu. When you receive a credential from a CA that you want to keep in the Microsoft Windows certificate database, install the certificate using the Windows Certificate Import Wizard. When you open a certificate file, click the Install Certificate button and follow the instructions in the Wizard.
