Device Manager will not launch from the Control Panel

If I go to Control Panel || System and Maintenance || System and select
Device Manager from the taks list, I get the following error message:

C:\Windows\System32\devmgmt.msc

This file does not have a program associated with it for performing this
action. Create an association in the Set Associations control panel.

I checked, and the *.MSC association is there. I can get to Device Manager
by going to the Run... dialog and typing "devmgmt.msc" and if I switch to the
Control Panel "Classic" view I can run Device Manager just by double-clicking
on it's icon.

How can I fix this??

Hi Speedy,

>> I checked, and the *.MSC association is there.

Some part of the .msc file class data may be missing. See if applying the .msc fix from here helps.

doesn't help. i tried even the "File association fixes for Windows Vista" fix File association fixes for Windows Vista
but doesn't help neighter.

i go to control panel, system, click on tasks: Device Manager and receive: c:\Windows\system32\devmgmt.msc
the file does not have a program associated with it.....

when i double click it in explorer, it opens correctly. when i right click on it open with, it reads microsoft management console...
the trouble is somewhere else...

Start > Run > regedit > navigate to

HKEY_CLASSES_ROOT\CLSID\{74246bfc-4c96-11d0-abef-0020af6b0b7a}\Shell\Open\Command

On The Right Pane The Default Value should read -
%SystemRoot%\system32\mmc.exe %SystemRoot%\system32\devmgmt.msc

well, i am back where i was. after reinstall!
i reinstalled Vista x64, applied sp1 rtm, and now, after one crash (now i know what drivers are they waiting for with SP1) am i back where i was - i cannot launch device manager from control panel/system.
i can launch it as C:\Windows\System32\devmgmt.msc or by any and all other methods, just not from there. funny, eh? will check with sysinternal registry/file monitors soon, i guess.

I have the same .msc problem
