    Hallo all, i am experiencing a very very unusual problem.

    i am using windows server 2003 datacenter r2 sp2 german edition. i have once
    live messenger 8.1 installed, it was completely ok. but now i would like to
    upgrade to 8.5, so first i uninstalled my messenger 8.1, but i just could not
    install version 8.5, it said something german like "the system has the
    installation rejected" or "denied". then i had no choice but again try to
    install version 8.1, but this time i had the same message "denied". so i
    found version 7.5 and the installation worked. but as we all know the version
    7.5 won't log on actually.

    i wondered what has happened. i checked the properties of the ".msi" file of
    version 7.5 8.1 8.5 and found that they both have digital certificate, but
    the names of the certificates are not the same:

    7.5 microsoft corporation MSN
    8.1 microsoft corporation
    8.5 microsoft corporation

    certificates with name "microsoft corporation" won't be accepted by my
    windows, the window "details of digital signatures" of the file property says
    something like "the certificate is blocked" or "denied" or "rejected" with a
    red "x" error symbol. but certificate with name "microsoft corporation MSN"
    of version 7.5 is completely ok. why? What should I do?

    The statements of this problem are above, please help me to solve it! Thank
