I have installed a cert. In Manage Private Keys I have added everything. Even then a web app hosted in IIS can't request successfully. The request was aborted: Could not create SSL/TLS secure channel error. This is only in Windows 7. Adding IIS_USRS in private key access works fine in Windows Server 2008. Any leads please?
I have seen almost everything about this and still can't figure it out.
Update: It is x.509 .p12 file.
Look here for thames' answer. He is a legend. Certs are more complex than they should be
