vshadow.exe 3.0 on windows vista x64

[Rami Abughazaleh]

Hello.

I'm using the Windows SDK for Windows Vista v6.1.6000.16384.

I compiled vshadow.exe v3.0 from here:
C:\Program Files\Microsoft SDKs\Windows\v6.0\Samples\WinBase\VSS\vshadow

using Visual Studio 2005 SP1 on Windows XP Professional x64 Edition
Version 2003 Service Pack 1

However, when I tried to run it on Vista x64 Ultimate Edition using a
command prompt elevated as Administrator, I get the following error:

C:\Users\Rami\Downloads>vshadow -q

VSHADOW.EXE 3.0 - Volume Shadow Copy sample client.
Copyright (C) 2005 Microsoft Corporation. All rights reserved.


(Option: Query all shadow copies)

ERROR: COM call "m_pVssObject->InitializeForBackup()" failed.
- Returned HRESULT = 0x8000ffff
- Error text: E_UNEXPECTED
- Please re-run VSHADOW.EXE with the /tracing option to get more details

running with the /tracing options produces the following:

Running it on Vista 32-bit Ultimate Edition works fine.

The 64-bit OS is a clean install with the default installation options.

After vshadow fails, I see the following errors in the event viewer:

Source: VSS
Event ID: 32
Volume Shadow Copy Service error: The VSS Coordinator class is not
registered. This may be caused due to a setup failure or as a result of
an application's installer or uninstaller.

Source: VSS
Event ID: 8193
Volume Shadow Copy Service error: Unexpected error calling routine
CoCreateInstance. hr = 0x80040154.

As a test, I tried to create a backup of all files on the system and
ntbackup did not fail when creating a shadow copy.

Any help is appreciated.

Thank you,
