Question

This is what happens:

Answer 1

Usually Certificates in Root won't have private key to manage. You should import to My folder if you are associating key in the web request. I have TLS/SSl exception where I have chain of client certificates. If you store all the chain of certificates in My store then I got rid of that exception. Where the problem is with user accounts. Utility to store the certificates uses current user account and the actual application runs on system account.
