It seems to need .NET 1.1 to access the Exchange mailboxes and public folders.  This is best done on an admin machine (not the Exchange server as installing v1.1 might break v2.0 and Exchange itself!).)

Download 1.1 and SP1 here:

Installing .NET on Vista x64 gives a compatibility error (with IIS), although installs okay.  See http://www.mydigitallife.info/2007/12/27/install-microsoft-net-framework-11-on-windows-vista-fix-regsvcsexe-fails-error/ for related (?) details.

Maybe error indexing an Outlook item?

net stop wsearch (might have to set service to "Disabled")

Regedit -> HKLM\Software\Microsoft\Windows Search

Give self Full Control -> "SetupCompletedSuccessfully" change to "0"

For each of following keys, give self Full Control and Take Ownership (& propogate), then delete

HKLM\Software\Microsoft\Windows Search\Applications\windows
HKLM\Software\Microsoft\Windows Search\CatalogNames\windows
HKLM\Software\Microsoft\Windows Search\Databases\windows
HKLM\Software\Microsoft\Windows Search\Gather\windows
HKLM\Software\Microsoft\Windows Search\Gathering Manager\Applications\windows
HKLM\Software\Microsoft\Windows Search\UsnNotifier\windows

rd %ProgramData%\Microsoft\Search\Data\Applications\Windows /S /Q

Set Windows Search to "Automatic"

net start wsearch

Check "SetupCompletedSuccessfully" now has value "1"

Won't run from Control Panel in Vista (x64).  System has quiet UAC prompts via GPO/gpedit.

Solution is to "run as administrator"; or WinKey -> wercon -> Ctrl-Shift-Enter

In Vista x64 after a while crashes, then won't (ever) scan more than two pages without crashing.

Seems disabling OCR in the scan profile gets around this (or creating a new OCR-less profile).#

Use launchapp

HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify

Delete keys 'IconStreams' and 'PastIconsStream'.

Kill and restart explorer process.

Need to use fsutil resource setautoreset true c:\ at elevated command prompt, reboot and install again.
