Device Manager will not launch from the Control Panel

[Speedy]

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.

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...

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

[R. C. White]

Hi, Mossi.

Since you did not quote any part of the prior discussion, we have no idea
what you might be talking about. :>(

Are you an Administrator of your Vista? Are you running as Administrator?

We are here because we want to help you. But you have to give us SOMETHING
to go on!

Hello,

I've had this problem and solved it after reading this link:
'Vista Device Manager link broken by notepad alternative, JujuEdit'
(http://channel9.msdn.com/ShowPost.aspx?PostID=361952)

The article says to carefully check what registry entries you have in
the
HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers tree

compare the keys you see on your computer with those from another clean
installation of Vista.

I've found a difference in the ContextMenuHandlers tree, I had a
registry key referring to a file called CopyPathExt.dll and after I
removed the registry key, the Device Manager in the System dialog box
link began to work again!!!

Attached is an image of the
HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers tree after removing the
CopyPathExt.dll mentioned above.
