Thanks for that Slipstick link. It has a wealth of useful information.
I am getting the Access Denied error when I try to install WDS3, and in
fact I don't even WANT to install WDS 3 (I use Google Desktop Search
and I like it), so here was the solution to that issue:
If you choose not to install WDS v3 beta, you'll see a yellow warning
at the top of your message list, along with a warning every time you
open Outlook or OneNote, that you need WDS installed. You can disable
this prompt using Outlook's Tools, Options, Other, Advance Options
dialog box if WDS is not installed. If the checkbox is missing from the
dialog you can edit the registry to disable it.
The registry key is:
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Search
DWORD: DisableSearchDownloadPrompt
Values: 1 = The WDS installation prompt and yellow bar are not
displayed
0 (or missing DWORD) The WDS installation prompt is displayed
You may need to restart Outlook to remove the yellow bar from the view.
As one of those who have the installer error, I disabled the prompt
rather than edit the registry to change the permissions. The time I
save with the instant search won't make up for the time needed to
enable it. I'll wait for an updated version of WDS that works.
