Windows Device Manager malfunction

[Guest]

I am having trouble with my mp3 player, when i contacted the company that
made it, they suggested that i see if it was listed under the device manager.
When I try to open it up however, i get an error message that says:
____________________________________________________________________
MMC cannot open the file C:\WINDOWS\system32\devmgmt.msc.

This may be because the file does not exist, is not an MMC console, or was
created by a later version of MMC. This may also be because you do not have
sufficient acess rights to the file.
____________________________________________________________________

As far as rights to acess go, I am the only user on this computer. I have
not touched the system32 file, so i dont understand what's going on. Does
anyone have a solution to this problem?

It is certainly possible to lock the only admin of a system out of the
system's control tools. If you also lack access to regedt32, and gpedit.msc,
I would say your access to that mp3 player (at the least) is toast. I would
install windows to a new folder, and 'take ownership' of the old data. (That
would require reinstalling all the other apps again, too)

Have you tried logging on to the system as the default "Administrator"
account?

CAUSE
This behavior occurs because the PATH environment variable does not include
the %SystemRoot%\System32\WBEM folder.

RESOLUTION
To resolve this behavior, add the %SystemRoot%\System32\WBEM folder to your
PATH environment variable. To do so, follow these steps:
1. Right-click My Computer, and then click Properties.
2. On the Advanced tab, click Environment Variables.
3. Under System Variables double-click the PATH environment variable.
4. Type:
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\system32\WBEM
Note If other system variables appear, do not remove them.
5. Click OK, and then click OK.

MMC cannot open Snap-in Name. This may be because the file does not exist,
is not an MMC console, or was created with a later version of MMC. This may
also be because you do not have sufficient access rights to the file.
Note In this error message, Snap-in Name is a placeholder for the name of
the MMC snap-in file, such as Compmgmt.msc.

CAUSE
This problem may occur when the following conditions are true:
* You configure the user of the %APPDATA% folder or you configure the system
environment variable to point to a location that is not available, such as a
network share.
* The Offline Files feature is turned off on your Windows XP-based computer.

WORKAROUND
To work around this problem, turn on the Offline Files feature on your
Windows XP computer. For additional information, click the following article

Make sure that %SystemRoot%\System32\WBEM is in the PATH.

Note: %SystemRoot% is usually the same thing as C:\WINDOWS

I.e. %SystemRoot%\System32 = C:\WINDOWS\system32

Open a command prompt...
Start | Run | Type: cmd | Click OK |
When the command prompt opens, type: path and then hit your Enter key.

It should look something like this...

PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem

There may be more items, but make sure that you see WINDOWS\System32\Wbem

This behavior can also occur if your PATH environment variable ends with \

To resolve the problem
1. Right-click My Computer and press Properties.
2. Select the Advanced tab.
3. Press the Environment Variables button.
4. Double-click PATH in the System variables area.
5. Remove the \ from the end of the string.
6. Press OK and OK.
