It sounds like your problem is a result of some of the older Beta versions
of WMDC interfering with the operation of the released version.
Can you look in Task Manager and tell me how much memory the wmdc.exe
process is taking up? If it's something small like 2 - 3MB, then the
"managed" portion of the process is failing to load. If everything is
working properly, the wmdc.exe process should have a memory footprint of
around 20 - 30MB (or larger). If your wmdc.exe process is only around 2 -
3MB in memory, please try the following workaround and see if it solves your
problem.
1. Open the registry editor (Run->Regedit)
2. Navigate to HKEY_CLASSES_ROOT\CLSID.
3. Completely delete the key titled,
"{3B5AA27A-CBF9-48C9-96F8-4ACE84FB8512}"
4. Open the Vista Control Panel and launch the 'Programs' applet.
5. Click the 'Uninstall a Program' link.
6. Find 'Windows Mobile Device Center' in the list of installed programs and
rigth-click it.
7. Select the 'Repair' option.
8. Reboot the PC just to be safe.

9. Connect your device and attempt to launch WMDC.
Let me know how this goes for you.

Hi Christian!
I upgraded from RC1 to RTM (build 6783) using the 32-bit version. The WMDC
UI is not visible, but the process is available in the Windows Task
Manager
after I manually is clicking on the shortcut from the desktop or from the
Control Panel\Network and Internet\Windows Mobile Device Center. The
ceappmgr
application is working fine, so there is no connectivity issue with the
device. Before I upgraded to Beta 2 I deleted the partnership with Outlook
and uninstalled the Active Sync. No partnership has been created with
WMDC.
I have completely uninstalled WMDC and reinstalling it several times using
the
- setup file in %windir%\WindowsMobile
- Windows Update
-
https://www.microsoft.com/windowsmobile/devicecenter.mspx,
but there are no changes in the behavior of WMDC.
In the %windir%\WindowsMobile folder I have created two config files as
described in the following link:
http://www.pocketpcfaq.com/faqs/wmdc/debug/index.htm, but no log files are
created in the TEMP folder, even if the WMDC process is running. Why is
there no log file created?

Nick,
It sounds like your device is successfully connecting with the sync
services. You can browse the device from 'Computer', it's visible in
WMP,
etc. So that rules out a connectivity issue.
Out of curiosity, are you running Vista 64-bit or 32-bit version? Also,
did
you ever set up a "Partnership" between your device and desktop in which
you
elected to sync Outlook or Exchange items?
Just so that I understand; you're saying that once you upgraded to RC1,
you
never saw a WMDC UI again? And you have upgraded RC1 to RTM (6783) and
still see no UI when you attach a device and manually launch WMDC using
the
shortcut or control panel applet?
Have you tried going to the 'Programs' control panel applet, completely
uninstalling WMDC and then reinstalling using
%windir%\WindowsMobile\setup.exe? If not, give that a try, reconnect
your
device and let me know how things go.

Hi Christian!
Thanks for your answer! Yes I have rebooted and reconnected my device
several times without solving the problem. I’m enable to synchronize
with
Media Player, but that is not desirable. I have all my contacts and
calendar
info in Outlook 2007 and have a wish to synchronize that some time. My
PC
as
been through an upgrade from XP SP2 with ActiveSync 4.2 and yes that
worked
excellent. In July 2006 I joined the Beta program of Vista and had to
uninstalled ActiveSync before the upgrade of Beta 2. The WMDC UI was
available, but I couldn’t sync with my device at all. When I so
upgraded
to
RC1 the WMDC UI disappeared and I haven’t seen it since. The WMDC
process
is
located in the task manager after I’m launching it manually and there
is
no
UI available.

Hi!
I’m having a problem starting WMDC. The process is located in the task
manager but there is no GUI available. I have uninstalled/reinstalled
several
times without getting any closer and there are no log files created
for
the
WMDC and WmdHost applications. All inbound/outbound WMDC ports on the
firewall are opened. When I attach my HTC TyTN running WM5 with the
USB
cable
an event warning with ID #4 from WcesComm is generated telling: “More
than
one Windows Mobile-based device cannot be connected at the same time.â€
Software:
Vista Ultimate latest version
Live OneCare version 1.5.1890.18
WMDC version 6.0.6783.0
