My VB6 addins install and run on Vista with no problems. However, I have had
lots of problems trying to run regsvr32 on Vista as an admin logon even with
user access control turned off. I can't help with Vista security.
I haven't tried using the new CDO in any of my addins, due to the
deprecation of CDO and security problems with CDO code due to the Outlook
object model guard I've done all my addin development using Redemption
(www.dimastr.com/redemption) as a replacement and more for CDO 1.21. I've
even translated most of my older addins to use Redemption code instead of
Another advantage of Redemption over CDO is I can use it with .NET projects,
it works there and CDO is not supported at all for .NET code.
