Hi. I'm using CertUtil to add a Certificate to a store, specific the following command: "certutil -addstore ROOT C:\certificate.p7b" When I execute this command in the "cmd" it show this message: "CertUtil: -addstore command completed successfully." The problem is that when I open the store, my certificate was not there. To see the store I'm using "certmgr.msc" and "certutil -viewstore ROOT". - I'm using Windows Server 2003 - I'm logged with an Administrator Account. - I've just tried in the "CA" store and "MY" store too. Important: the same command works perfectly in Windows Vista Anyone can help me, please? Thanks in advance.

Thanks Brian. I export using a DER format and it works good. Tiago
