    certificate


    Hi

    I have XP Pro x64 and I'm about to upgrade to Win7 Pro 64 bit.

    I am a little worried about what will happen to one security certificate that I use daily to access a particular website. I have Windows Easy Transfer installed. If I use this, will the certificate be copied accross properly into Win7 ?

    The certificate in question appears in the Certificates snap-in in MMC under
    Certificates - Current User - Personal

    Thanks

    you can export your certificates. Do that before upgrading. Then import it after.

    You're welcome :)

    Also, and this may go without saying but... make sure you export it to a safe location. Don't export it to a drive you're going to format or install Windows on. You can also password protect it if I'm not mistaken.

    Hi again

    I've now installed win7 and imported the certificate. However it doesn't seem to have worked correctly. When importing, I selected "personal" (it was a personal cert on my xp machine) and the import says it was successful, but it does not appear in the "personal" store - it appears in the "other people" store.

    I am now unable to access the website I need it for. I have tried to delete it, but it said I do not have permission to do so (!!) and I also tried re-importing it, but the exact same thing happened.

    Please urgently advise

    Thanks again

    Are you logged in as admin when trying to delete it?

    It sounds like you didn't export the private key along with the cert.

    A certificate is composed of public and private keys. You can't decrypt or sign messages without a private key.

    Yes I think so - Under "Make changes to your user account" it shows my account name, and below it says "Administrator" and below that "Password protected"
    If I click on "Manage another user account" the only other account present is "Guest"

    That rings a bell. When I exported it I noticed an option to export the private key, but it was greyed out and there was a note saying something like "the private key for this certificate cannot be exported".

    Hmm. Yes that's the problem then.

    Who issued you that certificate in the first place? Can you get another one?
