Using Xp Pro Sp3 with all updates. Want to copy my CA Root certificates to another computer. This is so I can access encrypted data saved on a USB drive. When I open the dialogue box I have 3. When I view the the Certs, I receive the error message “This CA Root certificate is not trusted. To enable trust, install this certificate in the Trusted Root Certification Authorities store.” I have read many solutions on the site and none work for this problem. How do I “install” this cert in the Trusted Root Certification Authorities store?
